  • Patent number: 11383615
    Abstract: An electric power supply system is to be included in a hybrid electric vehicle that is provided with a driving motor and an engine and is configured to switch between an HEV traveling mode of traveling by causing both the driving motor and the engine to operate and an EV traveling mode of stopping the engine and traveling with motive power of the driving motor. The electric power supply system includes a main battery, an electric power generator, a sub-battery, and a control apparatus. The main battery supplies electric power to the driving motor. The electric power generator generates electric power upon receiving motive power outputted from the engine. The sub-battery is charged with the electric power generated by the electric power generator. If an abnormality is diagnosed as being present in the sub-battery, the control apparatus disables the HEV traveling mode and enables the EV traveling mode.

  • Patent number: 11374426
    Abstract: A vehicle in which a contactless charger is installable, the contactless charger being capable of performing wireless charging of a mobile device. The vehicle includes a traveling controller and a device managing unit. The traveling controller is configured to perform at least traveling control of first traveling characteristics and traveling control of second traveling characteristics. The second traveling characteristics are traveling characteristics in which behavior of the vehicle is gentler than that in the first traveling characteristics. The device managing unit is configured to switch the contactless charger between a charging-capable state and a non-working state. When the device managing unit switches the contactless charger to the charging-capable state, the traveling controller changes traveling characteristics to the second traveling characteristics.

  • Publication number: 20220176964
    Abstract: A vehicle control system includes a target driving force calculator that calculates a target driving force of a vehicle, an arithmetic operator that calculates a request driving force and a request braking force, and a stop keeping processor that keeps the vehicle in a stopped state by increasing a brake fluid pressure so that a braking force becomes equal to or larger than a stop keeping braking force. The arithmetic operator executes a pressure pre-increasing process for pre-increasing the brake fluid pressure before a stop timing and setting, as the request driving force, a cancellation driving force for canceling a braking force for pressure pre-increase, and controls, in the pressure pre-increasing process, the request braking force so that the braking force for the pressure pre-increase is increased within a range in which the braking force does not exceed a braking force threshold smaller than the stop keeping braking force.
