摘要： A method and a control system for controlling movement of a vehicle to provide vehicle creep, the vehicle having an engine and an electric traction motor, and the control system having one or more controllers. The control system is configured to: while a torque path between the engine and a first set of vehicle wheels is disconnected, control the electric traction motor to provide tractive torque to a second set of vehicle wheels to automatically move the vehicle to provide electric vehicle creep. The electric vehicle creep is controlled by a mathematical model of engine creep torque that would be provided by the engine when the torque path between the engine and the first set of vehicle wheels is connected.

摘要： An acquirer acquires driving data of an electrically-powered moving body. A predictor predicts, based on the driving data of the electrically-powered moving body, an aging failure of an electromechanical transducer including a motor driving a driving wheel of the electrically-powered moving body and a drive circuit driving the motor. The driving data include an input voltage of the drive circuit, an input current of the drive circuit, a rotational speed of the motor driven by the drive circuit, and a rotational torque of the motor. The predictor predicts the aging failure of the electromechanical transducer based on a change of a value statistically representing a relationship between an input electric power of the drive circuit, obtained based on the input voltage and the input current of the drive circuit, and a shaft output power of the motor, obtained based on the rotational speed and the rotational torque of the motor.

摘要： Methods and systems are provided for determining a plurality of traction limits corresponding to each of a plurality of wheels of a vehicle and determining a grounded torque request. Based on the plurality of traction limits, the grounded torque request is distributed to each of the plurality of wheels. If a grounded torque request to a first wheel of the plurality of wheels exceeds a traction limit for the first wheel, the torque to the first wheel may be reduced, and an increased torque is applied to a second wheel of the plurality of wheels.

摘要： A vehicle includes a first axle provided with at least a pair of first wheels, and a second axle provided with at least a pair of second wheels. The second axle is a steered axle allowing said second wheels to be turned. At least one first electric machine provides propulsion torque to the first axle. At least one second electric machine provides propulsion torque to the second axle. A control unit is configured to control the first and second electric machines, wherein the control unit is configured to limit the propulsion torque provided by said at least one second electric machine in dependence of a current state of the second axle.

摘要： Systems and methods are provided herein for controlling the speed differential of wheels of a vehicle. The vehicle determines a wheel steering angle, where the wheel steering angle corresponds to a center of rotation of the vehicle. The vehicle determines a differential wheel speed associated with a first wheel of the vehicle and a second wheel of the vehicle based at least on the wheel steering angle. The vehicle independently applies torque to the first and second wheels based on the differential wheel speed.

摘要： A method of controlling an electric marine propulsion system to propel a marine vessel includes receiving a user-set time, determining a time remaining based on the user-set time, and identifying a battery charge level of a power storage system on the marine vessel. A required battery power is then determined based on the time remaining and the battery charge level, and then an output limit is determined based on the required battery power to enable propelling the marine vessel for the user-set time without recharging the power storage system. The propulsion system is automatically controlled so as not to exceed the output limit.

摘要： An embodiment oil temperature control system for an electric vehicle includes a heat exchange unit that performs heat exchange between an oil for cooling a driving motor and a coolant, a temperature sensor including an oil temperature sensor or an outside air temperature sensor, a controller that receives a signal from the temperature sensor to determine whether a heat generation mode entry condition to cause a power electronic part to generate heat is satisfied and operates the power electronic part in a heat generation mode when the heat generation mode entry condition is satisfied, and a cooling system that allows the coolant used to cool the power electronic part operating in the heat generation mode to circulate through a passage penetrating the heat exchange unit so that the coolant exchanges heat with the oil in the heat exchange unit.
