  • Patent number: 11897465
    Abstract: A vehicle control device includes a controller configured to control operation of a driving motor that is to output a driving force for a vehicle. The controller is switchable between a normal mode of controlling acceleration/deceleration based on a driver's acceleration/deceleration operation, and a cruise control mode of maintaining the vehicle speed at a target speed without the acceleration/deceleration operation. The controller is configured to, during the cruise control mode, calculate a torque command value for the motor by using integral control based on an integrated value of a deviation between the vehicle speed and the target speed, and execute an integrated-value adjustment process if the controller determines that the vehicle entered a flat road or an uphill road from a downhill road or a downhill road from a flat road or an uphill road. The process adjusts the integrated value to reduce an absolute value of the integrated value.

  • Patent number: 11900694
    Abstract: A parking assist system for a vehicle includes an environment information obtainer, a storage, a parked vehicle detector, a space determiner, and a parking possibility determiner. The storage stores a reference parking width to be used for parking the vehicle. The parked vehicle detector detects a parked vehicle. The space determiner compares a width of a space next to the parked vehicle with the reference parking width and determines whether the width of the space is greater than or equal to the reference parking width. If the width of the space is found to be greater than or equal to the reference parking width, the parking possibility determiner determines whether a target object is detected at a back side of the space. If the target object is not detected, the parking possibility determiner determines that parking in the space is prohibited.

  • Patent number: 11898929
    Abstract: A thermal management system includes a switching valve that switches between a first mode in which first and second flow paths are separated and a second mode in which parts of the first and second flow paths are connected. In the first mode, a control unit acquires measured values of first and second temperatures in the first and second flow paths and estimated values of the first and second temperatures when the switching valve is not in a slightly open state. The switching valve is in the slightly open state when the measured value of the first temperature is higher than the estimated value of the first temperature by a value greater than a first predetermined threshold and the measured value of the second temperature is lower than the estimated value of the second temperature by a value greater than a second predetermined threshold.
