Circuit Description ABS The ABS (Anti-Lock Brake System) control module controls the hydraulic brake pressure of all four wheels during sudden braking and braking on hazardous road surfaces, preventing the wheels from locking. The ABS provides the following benefits: (1) Enables steering around obstacles with a greater degree of certainty during panic braking. (2) Enables stopping during panic braking while allowing stability and control even on curves. In case a malfunction occurs in the anti-lock brake system, the system will operate as a normal brake system (fail-safe mode). A diagnosis function and fail-safe system have been included for serviceability. TCS The traction control is a variable system designed to enhance traction during acceleration and cornering. It does so by determining the optimum amount of wheel spin for any given driving situation, then suppressing surplus enginepower accordingly. The ABS control module gets signals about the vehicle's speed, direction and road conditions from | sensors at the wheels and the steering column. Based on these signals, the control module will determine the optimum amount ofwheel spin. Because the system is variable, the control unit may determine, depending on the driving conditions, that some wheel spin is beneficial (thus enhancing straight-line acceleration), or that no wheel spin is beneficial (thus enhancing cornering). For any given driving situation, the control module will determine the amount of wheel spin best suited to the driver's needs. The system is automatically ready whenever the engine is started, but can be manually canceled with theTCS switch. The TCS provides the following benefits. (1) When the drive wheel speed exceeds the vehicle speed by a given amount, the ABS control module judges that the drive wheels are slipping and it sends traction control signals to reduce engine torgue. (2) Based on the wheel speed sensor signals, the control module detects the condition of the road and then sends signals to improve acceleration efficiency and grip efficiency. |
