  • Patent number: 11745733
    Abstract: A vehicle control apparatus includes circuitry for controlling a vehicle. The circuitry is configured to search for a stop location where the vehicle is to stop, on a basis of road shoulder region information, generate an evacuation path on a basis of road information to the stop location, and guide the vehicle to the stop location from a first travel lane adjacent to a road shoulder region. The circuitry is further configured to calculate a collision risk of collision with an on-road obstacle. When the collision risk is a predetermined degree or higher, the circuitry is to interrupt the guidance, otherwise the circuitry is to guide the vehicle to enter the stop location and stop the vehicle at the stop location.

  • Publication number: 20210229705
    Abstract: In evacuation travel control, circuitry is configured to generate an evacuation route for evacuating the vehicle to the road shoulder area on the basis of road information and to control travel of the vehicle such that the vehicle travels on the evacuation route. The road information includes first information on a width of a road shoulder area along an end of the road in a width direction.

  • Publication number: 20210229702
    Abstract: A vehicle controller includes: a circuitry configured to generate an evacuation route to evacuate the vehicle to an evacuation position in a road shoulder area along an end of a road in a width direction on the basis of the road information stored in the memory and control travel of the vehicle such that the vehicle travels on the evacuation route while avoiding an on-road obstacle in the case where abnormality occurs to a driver. In the case where the vehicle does not reach the evacuation position within a specified target time from initiation of the circuitry to generate the evacuation route, the circuitry is configured to stop the vehicle in a travel lane.

  • Patent number: 9446758
    Abstract: A hybrid vehicle (100) is a parallel hybrid vehicle including a motor/generator (5) arranged between an engine (1) and a transmission (62). The engine (1) is configured to perform lean operation in a low-load operating range. The hybrid vehicle is configured such that a rotation speed at a maximum point of power generation efficiency of the motor/generator (5) is within a rotation speed range (Xa) corresponding to a lower-speed part (a) of a 95% fuel-consumption efficiency operating range (A) of the engine (1).

  • Patent number: 7520365
    Abstract: A steering apparatus for a vehicle, which can reduce the steering load and allows accurate steering angle control, is provided. In the steering apparatus for a vehicle, an estimation unit estimates a mechanical impedance upon a driver's steering manipulation. A control unit controls the steering reaction force of a steering wheel based on the estimated mechanical impedance.
