The system components consisted of a control switch, indicator light, four shock absorbers, shock absorber control actuator, shock absorber control computer, vehicle speed sensor, stop lamp switch, with a throttle position sensor and a steering angle sensor on TEMS three stage systems only. All the absorbers are controlled with the same level ...
An active suspension is a type of automotive suspension that uses an onboard control system to control the vertical movement of the vehicle's wheels and axles relative to the chassis or vehicle frame, rather than the conventional passive suspension that relies solely on large springs to maintain static support and dampen the vertical wheel movements caused by the road surface.
The earliest electronic systems available as factory installations were vacuum tube car radios, starting in the early 1930s.The development of semiconductors after World War II greatly expanded the use of electronics in automobiles, with solid-state diodes making the automotive alternator the standard after about 1960, and the first transistorized ignition systems appearing in 1963.
An electronic control unit (ECU), also known as an electronic control module (ECM), is an embedded system in automotive electronics that controls one or more of the electrical systems or subsystems in a car or other motor vehicle.
The active stabilizer system relies on vehicle body sensors and electric motors. The first production usage of this system was introduced in August 2005 with the Lexus GS430 sport sedan, [1] followed by the 2008 Lexus LS 600h luxury sedan. The development of APSSS is claimed to be the world's first electric active stabilizer system. [2]
The hydraulic control system of the 4F27E has six electronically controlled solenoids for shift feel (through line pressure control), shift scheduling (through shift valve position control) and TCC (torque converter clutch) apply, controlled by pulse-width modulation (PWM).
The systems harness various chassis sensors such as speed sensors, anti-lock braking system (ABS) sensors, accelerometers, and microcomputers to electronically monitor wheel slip and vehicle motion. When the chassis control system determines a wheel is slipping, the computer applies the brakes to that wheel.
Vehicle Dynamics Integrated Management (VDIM) is an integrated vehicle handling and software control system developed by Toyota. It involves an omnibus computer linkage of traction control, electronic stability control, electronic steering, and other systems, with the intent of improving responsiveness to driver input, performance, and overall ...
