    摘要： Both of a quiet operation with smaller torque variation for prioritizing NVH and a high torque operation or high output operation for prioritizing torque or output may be provided by selectively using, based on requests, a control scheme that reduces torque variation and a control scheme that maximizes a torque. A motor current calculator (12) may be capable of selectively using an output prioritizing control scheme that prioritizes a torque output and a torque variation suppressing control scheme that prioritizes smaller torque variation. An output requirement determiner (13) may be provided to calculate a degree of importance of suppressing torque variation of an electric motor (14), based on one or both of a braking request and a travel condition of a vehicle. In accordance with this determination result, the motor current calculator (12) may selectively use the output prioritizing control scheme and the torque variation suppressing control scheme.

    摘要： A vehicle includes a tone wheel having a plurality of encoding members spaced substantially evenly about a periphery thereof. Each tone wheel is rotates with an associated wheel. A fixed speed sensor is mounted adjacent to each tone wheel. The vehicle includes a brake system. A method determines a travel distance between adjacent encoding members. A required rolling distance of a vehicle from standstill is established. Maximum allowed interrupts per wheel is established, with an interrupt defined as each instance an encoding member passes an associated speed sensor. It is determined whether the vehicle is actually rolling from standstill. Once the vehicle is actually rolling, a number of interrupts is counted at each wheel. When the maximum allowed interrupts is counted at each wheel, the brake system is supplied with pressure increase to return the vehicle to, and hold the vehicle at, standstill prior to reaching the required rolling distance.
