  • Patent number: 11326656
    Abstract: A method for controlling an actuator of an actuator unit of a motor vehicle includes detecting desired activation of the actuator, detecting whether a currently present operating state of the motor vehicle is a first operating state or a second operating state, selecting either a first control routine upon detecting the first operating state or a second control routine upon detecting the second operating state, and actuating the drive motor with the selected first control routine or second control routine. A drive motor of the actuator unit is controlled depending on the operating state of the motor vehicle. In the first operating state, an actuation of the actuator occurs according to the first control routine with high dynamics of the drive motor, and in the second operating state, the actuation of the actuator occurs according to the second control routine with adjusted dynamics of the drive motor.

  • Patent number: 11326691
    Abstract: A belt-type continuously variable transmission includes a primary pulley, a secondary pulley, and a belt wound around the primary pulley and the secondary pulley. A controller performs a process, when performing a low speed position return shift to shift a transmission ratio toward a lowermost speed position while a vehicle is decelerating. The process includes: calculating a primary pressure actual lower limit, at which the belt actually starts to slip, based on the transmission ratio and a deceleration of the vehicle; setting a lower limit of a setpoint of the primary pressure to the primary pressure actual lower limit; setting the primary pressure actual lower limit higher with a locking tendency of a vehicle wheel detected than that without the locking tendency detected; and setting the primary pressure actual lower limit with the locking tendency detected to increase as the transmission ratio varies toward the lowermost speed position.
