  • Publication number: 20200039512
    Abstract: A control unit functionally comprises a first steering-torque application control part which commands a steering actuator of a vehicle to execute application of a steering torque determined by a first steering characteristic CH1 and a second steering-torque application control part which commands the steering actuator of the vehicle to execute application of a steering torque determined by a second steering characteristic CH2. The first steering characteristic CH1 comprises plural characteristics CH1A-CH1J which have different steering torques changing according to a vehicle speed. The characteristics CH1A-CH1J are set according to the vehicle speed such that these gradually change in a manner CH1A?CH1J as the vehicle speed becomes higher. The steering torque applied to the steering wheel is set such that the higher the vehicle speed is, the smaller the steering torque is, as shown by the characteristics CH1A-CH1J.

  • Publication number: 20200001916
    Abstract: A vehicle control processor and method capable of preventing departure to an off-road, to reduce driver discomfort, irritation and stress. The control processor calculates a width of a side strip between a left mark line and a road end based on information from a camera. When the width is wider than a specified width, steering torque based on first and second steering characteristics are exerted. The steering torque based on the first steering characteristic is exerted when a vehicle lateral end is located within a range from a left mark line outer end to a characteristic switching position, set in accordance with the width of the side strip between the left mark line and the road end, and the steering torque based on the second steering characteristic is exerted when the vehicle lateral end is located within a range from the characteristic switching position to the road end.

  • Patent number: 10414394
    Abstract: ECU 10 is configured to detect an object external to the vehicle 1, and determine a speed distribution area 40 for defining a distribution of an allowable upper limit of a relative speed of the vehicle 1 with respect to the object in a travelling direction, in a range from a lateral area to rearward and forward areas of the object in the travelling direction. The speed distribution area is determined such that the allowable upper limit is made lower as a lateral distance and a longitudinal distance from the object become smaller. When objects (8A, 8B) are detected, respective ones of the speed distribution areas (40A, 40B) for respective ones of the objects are set, the relative speed for each of objects is calculated, and an avoidance control is executed for restricting the relative speed from exceeding the allowable upper limits.
