  • Patent number: 11325600
    Abstract: The present invention provides a vehicle control method capable of suppressing an increase in the frequency of stopping and restarting of the engine when the braking device is activated at the self-driving mode. When the operation mode is set as self-driving, the braking device is activated in accordance with a system deceleration request to keep an actual vehicle-speed at a target vehicle-speed or change the actual vehicle-speed at the target vehicle-speed or lower depending on environment surrounding the vehicle. Further, a braking amount is estimated, the braking amount is a magnitude of a braking force generated from the activated braking device. When the braking amount is an engine-stopping enabling threshold or more, enabling stopping is allowed. When the braking amount is less than the engine-stopping enabling threshold, enabling stopping is not allowed.

  • 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.

  • Publication number: 20220140766
    Abstract: A power control method for calculating a duty command value to be used for a PWM control, generating a PWM signal corresponding to a comparison result between the duty command value and a carrier signal, and applying a PWM voltage to a load by driving an inverter based on the PWM signal. The power control method comprises obtaining a compensation amount according to a phase shift generated in the PWM voltage so as to compensate for the shift, correcting the compensation amount according to a cycle of the carrier signal, and correcting the duty command value depending on whether a strength of the carrier signal is increasing or decreasing using the corrected compensation amount.

  • Patent number: 11318840
    Abstract: A vehicle travel control method and a vehicle travel control device carries out a downshift control of an automatic transmission when a vehicle speed increases from a set vehicle speed during a constant speed travel control by at least a first prescribed value. Subsequent downshift control of the automatic transmission is prohibited upon determining the vehicle speed has increased from the set vehicle speed by at least the first prescribed value due to an operation of an operating element by the driver during constant speed travel control. Downshift control of the automatic transmission is executed upon determining insufficient deceleration of the vehicle exists where the driver is not operating the accelerator pedal during prohibition of the downshift control.
