Chassis Electronics

FUJITSU electronic systems address three key areas of vehicle chassis dynamics: braking systems, steering control and suspension. They contribute to innovations such as electronic stability control (ESC) and the Electronic Stability Program (ESP).

By improving upon established technologies such as anti-lock braking and traction control, they ensure safe driving conditions by correcting over-steer and reducing engine torque where required: even taking control themselves when conditions are critical.

ESP systems utilizing FUJITSU solutions compare driver inputs from the steering wheel with feedback from sensors in the wheel hub and underside of the vehicle. Steering wheel angles measure the driver input, while accelerometers and gyro sensors measure the vehicle response. Also, by connecting the ESP controller to the power train ECU, the element of traction control can be implemented.

FUJITSU not only manufactures microcontrollers for main chassis control and sensor subsystems, but also offers a range of gyro sensors and accelerometers for use in these safety-critical systems. The FUJITSU 8, 16 and 32-bit microcontroller families embody a range of peripherals such as PWM outputs and on-chip analogue-digital converters, together with automotive interfaces for communicating with CAN and LIN in-vehicle networks. Next-generation devices for FlexRay and other high-performance applications are under development.
