A method includes controlling a torque output of an electric machine of an electrified vehicle based on estimated loads present during a transmission engagement of the electrified vehicle. Controlling the torque output may include merging a first feed-forward torque with a feedback torque if an input shaft of a transmission gearbox is spinning, or merging a second, different feed-forward torque with the feedback torque if the input shaft is not spinning.

A vehicular control apparatus that includes a switched reluctance motor and an electronic control unit is provided. The switched reluctance motor has a rotor and a stator and is mounted as a travel drive source in a vehicle. The electronic control unit executes current control of the switched reluctance motor. The electronic control unit executes first current control for causing the rotor to rotate in a reverse direction from a rotational direction in which the vehicle is started in the case where the vehicle is not started even when the switched reluctance motor outputs maximum torque within an allowable range, and executes control for causing the rotor to rotate in the rotational direction in which the vehicle is started after the rotor rotates in the reverse direction by the first current control to a rotation position at which torque for enabling a start of the vehicle can be output.

A control device of an electric vehicle includes: an information acquiring portion acquiring information in a switching control of traveling modes of the electric vehicle and information on a gradient of an uphill road; a balanced driving force calculating portion determining that the electric vehicle is stopped on the uphill road in a motor traveling mode and calculating a balanced driving force against a sliding-down force causing the electric vehicle to be slid down; a temperature change estimating portion estimating changes of temperatures of the motor and the inverter; a time calculating portion calculating a drivable time until the temperature of the motor reaches a motor-side upper limit allowable temperature and an energizable time until the temperature of the inverter reaches an inverter-side upper limit allowable temperature; and a mode switching portion switching the motor traveling mode to another traveling mode.

A technique controls regenerative braking to reduce skidding of an electric vehicle. Such a technique may involve imparting rotation to an electric motor to move the vehicle to a first speed; and adjusting the limit regenerative braking power available based on a grade/slope on which the vehicle is operating. Processing circuitry may be configured to both: (a) allow a vehicle to have unrestricted or less restricted regenerative braking for more quickly slowing the vehicle when desired such as on flat dry pavement and/or on flat ground, and (b) limit, or more significantly limit, the vehicle's deceleration in situations such as when traveling downhill on a steep grade to reduce chances of sliding/skidding.

This vehicle control device comprises: a slope movement start assistance unit that maintains a braking force until elapse of a predetermined period since execution of a braking release operation for releasing a braking force applied to the wheels of a vehicle equipped with a motor serving as a power source such that the vehicle does not go down a slope; an acquisition unit that acquires each of the gradient of a road surface on which the vehicle is stopped and the total weight of the vehicle; and a control unit that executes control for causing the motor to generate, in the predetermined period, a threshold torque that corresponds to each of the gradient of the road surface on which the vehicle is stopped and the total weight of the vehicle.

A method according to an exemplary aspect of the present disclosure includes, among other things, controlling a torque output of an electric machine of an electrified vehicle based on estimated loads present during a transmission engagement of the electrified vehicle.

Various disclosed embodiments include illustrative systems for performing hill stall/start assist functions. An illustrative drive unit controller receives a zero-speed command and electric motor information, generates a torque command based on the received zero-speed command and the electric motor information, and instructs a drive unit inverter for an electric motor in response to the generated torque command.

Disclosed is a travel control method and apparatus. A travel control method and apparatus according to the present embodiment includes detecting a travel speed of an industrial vehicle, detecting a gradient of a road surface, setting an accel drive function of the industrial vehicle to be turned on or off, and controlling driving of a travel apparatus on the basis of a state in which the accel drive function is turned on or off.

A vehicle has a driveline which comprises a motor configured to provide a propulsion force to propel the vehicle, a pedal configured to control a power provided by the motor when a driver press the pedal to tilt the pedal in different positions, and a control unit configured to limit, at standstill, in function of an estimation of a weight of the vehicle. The propulsion force is provided by the driveline to a maximal force threshold value. The control unit adapts, at standstill, the pedal mapping so that each position of the pedal corresponds to a predefined percentage of the maximal force threshold value, independently of the maximal force threshold value. The maximal force threshold value is calculated as a function of the weight of the vehicle, a reference inclination of the road and a reference acceleration of the vehicle.

When there is backlash in a rotation direction between a lock member at a lock position and a first rotary member, a rotational position of a target rotary member, the rotational position being detected in a locked state of a parking lock mechanism by a rotational position sensor, is defined as a detected rotational position, and a rotational position of the target rotary member in a case where it is assumed that there is not the backlash in the locked state of the parking lock mechanism is defined as a theoretical lock position, a control device executes torque direction determination processing that determines a wheel torque direction, on the basis of a direction of deviation of the detected rotational position from the theoretical lock position due to the backlash.
