Title: Vehicular braking controller
Inventor: HARA MASAHIRO
IPC: B60T8/94
Filed: 2001-05-30
Abstract: PROBLEM TO BE SOLVED: To minimize deterioration of vehicular braking control performance when an anomaly occurs in a pressure sensor detecting a wheel cylinder pressure. SOLUTION: A target wheel cylinder pressure Pti is calculated in response to a braking manipulated variable of a driver (S20). When anti-skid control is necessary, the target wheel cylinder pressure Pti for reducing slips is calculated (S40 and 50). A target driving current It to a linear valve is calculated on the basis of a deviation between the target wheel cylinder pressure Pti and an actual wheel cylinder pressure Pi (S70). When the pressure sensor is normal, the linear valve is control on the basis of the target driving current It (S30 and 80). If there is an anomaly in the pressure sensor, the linear valve is intermittently opened and closed so that the wheel cylinder pressure Pi becomes the target wheel cylinder pressure Pti (S30 and 90-150).
