Title:
CREEPING-CUT CONTROL APPARATUS FOR ELECTRICALLY DRIVEN VEHICLE
Document Type and Number:
WIPO Patent Application WO/2012/002049
Kind Code:
A1
Abstract:
Provided is a creeping-cut control apparatus, wherein, when a vehicle in a state of outputting forward movement creeping torque slides down in a backward direction indicated by a change in the vehicle speed (VSP) with the elapse of time, the sliding down in the backward direction is detected by [vehicle speed (VSP) < (-V1)] (t1), and when this state continues for a predetermined period of time that corresponds to a timer setting value (NTM1) (t2), creeping-cut is prohibited by setting [creeping-cut prohibition flag (NFLAG) = 1]. Therefore, when braking needed for preventing the vehicle from moving in the above-mentioned backward direction is started at t3, and the vehicle speed (VSP) becomes a value in proximity to 0 at t5, creeping-cut will not be executed even when the conventional creeping-cut permission flag (FLAG) is set to 1, and further, creeping torque will be continued to be outputted even after t5, to prevent a decrease in creeping torque starting at t5 due to an execution of creeping cut, which may introduce an uncomfortable feeling.
