Function
|
|
DSC HU/CM
|
• Calculates input signal from each sensor, and controls brake fluid pressure applied to each wheel, and activates each DSC system function (ABS, EBD, TCS, and DSC).
• Outputs control signal regulating the function of the TCS/DSC system and speed signal through CAN.
|
|
• Controls the diagnosis system and fail-safe function when an abnormality is detected in the DSC system.
|
|
PCM
|
• Controls engine torque based on the signal from DSC HU/CM.
• Transmits engine conditions and tire information to DSC HU/CM through CAN.
|
|
DSC indicator light
|
• Notifies driver of DSC operation (Vehicle is in side slip situation).
• Notifies driver of TCS operation (Drive-wheel slippage situation).
|
|
DSC OFF switch
|
• DSC system non-operation based on driver intention is transmitted to DSC HU/CM.
|
|
DSC OFF light
|
• Notifies driver of DSC system non-operation by DSC OFF switch.
• Notifies driver of DSC system is forbidden by fail-safe function.
|
|
ABS wheel-speed sensor
|
• Detects rotation state of each wheel and transmits signal to the DSC HU/CM.
|
|
Combined sensor
|
• Detects lateral-G force, forward-G force (4WD) and yaw rate (vehicle cornering angle velocity) of vehicle and transmits to DSC HU/CM.
|
|
Brake fluid pressure sensor
(Built-in DSC HU/CM)
|
• Detects fluid pressure from the master cylinder.
|
|
Steering angle sensor
|
• Detects steering angle and transmits to the DSC HU/CM.
