The all-new Mazda BT-50 has the latest safety features seen in
passenger cars. It also embodies comprehensive safety measures
specific to utilities trucks.
Some of the safety features are designed for active safety; the
all-new BT-50 enable the driver to avoid hazards and accidents by
creating an environment in which the driver has good visibility and
can control the vehicle easily, by handling responsively, having
high levels of stopping power, and by having vehicle control
technologies that work together to maintain controllability in
diverse driving conditions.
The vehicle control technologies are not limited to commonly
used ones such as a Dynamic Stability Control (DSC) system and a
four-wheel Antilock Braking System (ABS) with Electronic
Brake-force Distribution(EBD); they also include state-of-the art
technologies such as a Trailer Sway Control function.
Passive-safety features protect users of the new BT-50 in the
event of an unavoidable accident. They include a sturdy body and
frame, which both incorporate reinforcements that reflect
comprehensive impact analysis; front, side, and curtain SRS
airbags; and all-seat three-point seatbelts with pretensioners and
load limiters for the front seats.
The new BT-50 meets stringent national and international
standards with near-segment-topping levels of impact safety. It
also reflects efforts to protect pedestrians and efforts to ensure
safety for children in the cabin.In a concerted effort to fully
protect all occupants, Mazda devoted serious effort toward
improving the active safety technologies that help drivers avoid
collisions and foresee potential hazards, and also the passive
safety technologies that reduce the chance and severity of injury
in the case of an unexpected accident.
Of course, the measures taken are all linked directly to the
"driving pleasure" at the heart of Mazda's Zoom-Zoom concept.
Phrased differently, we believe that to achieve true driving
pleasure we must establish a strong sense of oneness between driver
and car. This consists of the driver's capability to perfectly
control the car, as well as improved safety performance and a more
confidence-inspiring ride feel. The concepts of "driving pleasure"
and "safe and confident driving" do not stand in opposition to one
another. Rather, they are synonymous concepts that go hand in
hand.
Vehicle Control Technologies
Since utilities are used under diverse loading conditions, the
all-new BT-50 not only features skid-prevention and
traction-control functions like those of passenger cars; it also
has state-of-the-art control functions that effect vehicle control
and prevent a rollover in accordance with load, suppress swaying of
trailers, and make hill starts easy.
Antilock Braking System (ABS) with Electronic
Brake-force Distribution (EBD)
The ABS prevents the wheels from locking in the event of hard
braking on wet or otherwise slippery roads, so it helps the driver
stay in control and avoid hazards. A related EBD function senses
the vehicle speed and the load applied to the rear wheels by the
contents of the cargo box and accordingly optimizes the
distribution of braking force to the front and rear wheels to help
minimize braking distances.
Traction Control System (TCS)
The TCS senses the driven wheels' tendency to lose grip and
start spinning during standing starts and acceleration, and it
controls the output of the engine and/or applies the brakes to the
wheelspin-prone wheels to prevent wheelspin and achieve optimal
traction.
Dynamic Stability Control (DSC)
The DSC system works with the ABS and TCS to optimally control
the output of the engine and the braking force applied to each
wheel so as to prevent skids. It keeps the vehicle stable during
cornering manoeuvres on slippery roads and when the driver turns
the steering wheel hard to avoid hazards.
For example, it prevents understeer from leading to a
front-wheel skid by reducing the engine output and applying braking
force to the inner rear wheel; and it prevents oversteer from
leading to a rear-wheel skid by applying braking force to the outer
front wheel.
Emergency Brake Assist (EBA)
The EBA function senses how far and how quickly the driver
presses the brake pedal. If it recognizes emergency braking, it
helps the driver by maximally boosting the effectiveness of the
brakes.
Brake Override System (BOS)
If the driver accidentally presses the brake and accelerator
pedals at the same time, the BOS prioritizes the brakes such that
the vehicle comes to a stop.
Load Adaptive Control (LAC)
The weight and position of cargo affect the vehicle's mass and
centre of gravity. The LAC function senses changes in the vehicle's
mass and centre of gravity and adapts the operation of theABS, TCS,
and DSC system to maximize braking effectiveness, traction, and
stability. It also reduces the risk of a rollover.
Trailer Sway Control (TSC)
If a trailer starts swaying owing, for example, to a gust of
wind from either side, the TSM function controls the speeds of
rotation of the vehicle's left- and right-hand wheels in order to
suppress the swaying and promote stability.
Roll Stability Control (RSC)
Cargo can give a pickup truck a high centre of gravity. The ROM
function monitors the vehicle's behaviour from the vehicle speed,
steering angle, and yaw rate and brakes individual wheels as
necessary to prevent the vehicle from rolling over.
Hill Launch Assist (HLA)
When the driver moves his foot from the brake pedal to the
accelerator pedal for a hill start, the HLA function keeps the
brakes applied until the vehicle starts moving. The HLA function
thereby prevents the vehicle from rolling backward.
The HLA function automatically starts working if an acceleration
sensor indicates a certain road gradient (7% or steeper with an
automatic transmission; 4% or steeper with a manual transmission).
It keeps the brakes applied for up to two seconds until there's
enough engine torque for the hill start. The result is a safe,
smooth hill start.
Hill Descent Control (HDC) (4x4 models
only)
The HDC function automatically applies the brakes to keep the
vehicle moving steadily at a predetermined speed during downhill
driving. It's particularly effective during off-road driving. It
enables the vehicle to move downhill slowly and safely without
requiring the driver to press the accelerator and brake pedals.
Collision safety
The all-new Mazda BT-50 embodies numerous measures to realize
superior protection in diverse types of collision, to satisfy tough
national and international standards, and to achieve high ratings
in assessment programs for new cars. Increased body and frame
rigidity suppresses cabin deformation in the event of a collision.
Rigigidity was increased by adding crossmembers in the vicinity of
the cabin floor and by increasing the cross-sectional dimensions of
members carried forward from the outgoing BT-50. Reinforcements to
the tunnel and side sills were also added and the cross-sectional
dimensions of the reinforcing structures were increased in the
A-pillars of all body types and in the B-pillars of the Dual Cab.
In addition, 1,180MPa ultrahigh- tensile steel was used for the
rocker panels.
The new BT-50's bodyshell has higher flexural and torsional
rigidity. The new Dual Cab's bodyshell has about 20% more torsional
rigidity than the current one.
Strong crossmembers were placed in positions where they form the
ideal load paths to disperse frontal impact forces for absorption
by the entire frame.
Various items of up-to-date passive-safety equipment complement
the sturdy frame and highly rigid body to protect occupants in the
event of an accident.
Passive safety
Seatbelts
The driver's seat and front passenger seat each have a 3-point
Emergency-Locking-Retractable (ELR) seatbelt with a pretensioner
and a load limiter. The pretensioners ensure rapid restraint in the
event of a collision. The load limiters then loosen the belts to
mitigate chest impact. There's also a seatbelt reminder. Each of
the three rear seating positions in the Dual Cab has a three-point
ELR seatbelt.
Airbag system
For chest and head protection in the event of a frontal or side
impact, the all-new BT-50 has driver and passenger front airbags,
side airbags, and curtain airbags. The curtain airbags extend as
far as the rear seat.
Shock-absorbing steering column
In the event of a frontal impact, the steering column moves
forward to mitigate the impact of the steering wheel on the
driver's head and chest.
Crushable brake pedal
A crushable brake pedal prevents pedal-inflicted foot and leg
injuries in the event of a frontal impact. As the dash panel is
pushed toward the driver's seat by the engine, the pedal's support
bolt is pushed out of position, freeing the pedal and thereby
limiting the extent to which the pedal is pushed toward the
driver.
Shock-absorbing door structure
The doors each incorporate a plastic pad known as a pusher
block, which protects the nearest occupant's abdomen and lower back
in the event of a side impact. During a side impact, the pad
touches the seat, causing the impact force to pass into the seat
and thereby limiting the extent to which the door intrudes into the
cabin.
Pedestrian Protection
The new BT-50 is designed to minimize the extent of injuries in
the event of contact with a pedestrian. A honeycomb structure in
the bonnet absorbs and disperses the force of any contact with a
pedestrian's head. And urethane foam behind the front face of the
front bumper mitigates the force of any contact with a pedestrian's
knees.
