摘要： When a hybrid vehicle travels in CS mode in EV single-drive mode, when a required torque is larger than a torque threshold or when a required power is larger than a power threshold, and when a predetermined high response request is not being issued, a drive mode is caused to shift into HV drive mode. When the predetermined high response request is being issued, the drive mode is caused to shift into EV double-drive mode.

摘要： A wheel stability control system for an electric vehicle including an electric motor, a drive inverter, and an electronic control unit (ECU) including a computer readable, non-transitory memory (memory) and an electronic processing unit (EPU). The memory stores information including an optimal acceleration and deceleration curve and the electrical characteristics of the electric motor. The EPU calculates the electrical moment of the electric motor from inputs from the drive inverter and the electrical characteristics of the electric motor. The ECU compares the electrical moment and the angular speed of the motor with the optimal acceleration and deceleration curve, and if the acceleration or deceleration of the electric motor is out of a predetermined range when compared to the optimal acceleration and the optimal deceleration, it reduces the electrical moment applied by the electric motor.

摘要： A method for operating a recuperation brake of a motor vehicle is disclosed. First, a future operating intensity of the recuperation brake is estimated for a section of route to be travelled on by the motor vehicle based on an input which characterizes the driving style of the section of route to be travelled on. In addition, a maximum slip-free vehicle braking power for the section of route is estimated as a function of the input. In addition, the braking power of the recuperation brake is set to a setpoint braking power which is not greater than the maximum vehicle braking power for the section of route, and finally the recuperation brake is activated on the section of route to be travelled on with the setpoint braking power. In addition, a recuperation brake for carrying out the method is described.

摘要： A traction motor system calculates motor flux by generating a real time effective resistance of a resistance grid calculated from motor torque and measured voltage on a DC link. Calculating effective resistance avoids solely relying on DC link voltage, which can be influenced by conditions such as wheel slip and drop out of one or more resistance grids. The effective resistance calculation is based on nominal motor values using known power levels and conditions. From these nominal values and the effective resistance, various scaling factors based on actual motor power can be generated and used to adjust a nominal flux reference to more accurately reflect actual motor flux. The scaling factors include power and torque scaling factors and a resistance scaling factor that is active during conditions such as wheel slip.

摘要： An object of the invention is to increase the recovered kinetic energy as much as possible in a regeneration control system for a vehicle that converts the kinetic energy of a wheel into electrical energy while the vehicle is decelerating. To achieve the object, in the invention, the electric energy generated by a generator is decreased at the time when the wheel slips. In consequence, the recovered kinetic energy can be made larger as compared to the case where the electric energy generated by the generator is decreased based on an anticipation of slippage of the wheel made in advance.

摘要： Provided is a vehicle skid control device that avoids a skid erroneous judgment in a high revolution range of a motor. The vehicle skid control device detects the number of revolutions of the motor. When the number of revolutions of the motor is equal to or larger than a predetermined threshold value Nm, the vehicle skid control device prohibits a skid judgment. When the number of revolutions of the motor is smaller than the predetermined threshold value Nm, the vehicle skid control device permits the skid judgment. When the number of revolutions of the motor is equal to or larger than the threshold value Nm, the skid judgment is prohibited. Accordingly, it is possible to avoid the skid erroneous judgment in the high revolution range with the number of revolutions equal to or larger than Nm.
