CREEP CUT-OFF CONTROL DEVICE FOR ELECTRIC VEHICLE |
摘要 |
In a forward creep torque output condition, vehicle speed (VSP) enters a vehicle speed range in which creep cut-off is prohibited (t1) of less than V1, and if this condition continues only for a set time (t2) corresponding to a timer value (NTM1), creep cut-off is prohibited by a creep cut-off prohibition flag (NFLAG=1). Consequently, while the vehicle speed (VSP) is around 0, and a creep cut-off clearance condition related to the vehicle speed holds true, a braking force is at least equal to a creep cut-off clearance braking force, and the creep cut-off clearance condition related to the braking force holds true (t3). Even if a creep cut-off clearance flag (FLAG) is set to 1 at t4 in response to this, creep torque continues to be output from t4 onward without creep cut-off being carried out in response to this, enabling the occurrence of an unreasonable torque reduction due to the execution of creep cut-off at t4 to be prevented. |
