In a vehicle driving assist device including a control device, the control device is configured to set, in steering assist control, an upper limit value of a steering angle in a counterclockwise direction as a left limit steering angle or an upper limit value of the steering angle in a clockwise direction as a right limit steering angle. When the steering angle exceeds the left limit steering angle in the counterclockwise direction, the control device is configured to apply an assist steering force in the clockwise direction to a steering operation. When the steering angle exceeds the right limit steering angle in the clockwise direction, the control device is configured to apply the assist steering force in the counterclockwise direction to the steering operation.

Vehicle driving assist device, vehicle driving assist method, and non-transitory storage medium

A control device for a vehicle configured to execute a first control for outputting a steering torque based on a predetermined first gain and a second control for outputting a steering torque based on a predetermined second gain different from the first gain, wherein during execution of the first control, a predicted start time, which is a predicted time until the start condition of the second control is satisfied, is calculated, and when the start predicted time satisfies the predetermined condition, a reduction control for bringing the output steering torque of the first control closer to 0 is executed before starting the second control.

Control device for vehicle and control method for vehicle

A driver assist system for avoiding hunting of an assist control. The driver assist system comprises: an edge line detector that detects edge lines of a predetermined lane; a limit steering angle detector that detects a limit steering angle at which a vehicle reaches the edge line in a predetermined time; an actual steering angle detector that detects an actual steering angle from a reference position; a comparator that compares the actual steering angle with the limit steering angle; a steering assistor that establishes a steering reaction force when the actual steering angle exceeds the limit steering angle; a determiner that determines a satisfaction of a condition relating to a lane width; and an adjustor that imaginarily sets the right edge line and the left edge line on the center of the lane, and calculate the limit steering angle based on the imaginary edge line upon the satisfaction of the condition.

Driver assist system for vehicle

A driving assistance system includes: a first control unit configured to output an output amount related to a required amount; and a second control unit configured to calculate a difference amount between the output amount output and an actually measured amount of an actuator, and control the actuator based on the difference amount and a torque map, in which in assist control (second driving assistance control), the first control unit calculates a difference amount between a second required amount and the actually measured amount, acquires a division amount by dividing the difference amount by a predetermined value, and outputs a total amount of the division amount and the actually measured amount as the output amount, and the second control unit calculates a difference amount between the total amount and the actually measured amount, and controls the actuator based on the difference amount and a second torque map.

Driving assistance system

A control device for a vehicle including an operation unit that receives an operation for setting ON or OFF of a plurality of driver assistance functions, wherein at least two or more driver assistance functions among the plurality of driver assistance functions are driver assistance functions classified into a specific group in which the degree of intervention of control for the driving operation is smaller than other driver assistance functions, and the operation unit includes a main switch for collectively setting ON or OFF of the driver assistance functions classified into the specific group.

Control device for vehicle

A control unit that controls a reaction force actuator that applies steering guide torque to a steering wheel: calculates, based on a curvature of a curve of a travel road in front of a vehicle detected by a camera sensor, a target steering angle for causing the vehicle to travel along the curve; calculates a target steering guide torque, based on a deviation between the target steering angle that was calculated a prediction time period earlier and an actual steering angle; adjusts a target steering guide torque such that the target steering guide torque becomes smaller as a probability that a driver performs steering operation to deviate from a lane becomes higher; and controls the reaction force actuator such that the steering guide torque becomes the target steering guide torque.

Vehicle steering guide torque control apparatus

A seat control apparatus controls a seat of a vehicle in which an occupant of the vehicle sits. The seat control apparatus includes an occupant weight recognition unit; an occupant sitting state recognition unit configured to recognize an occupant sitting state including at least either of a grip force of the occupant and a load applied to the occupant; a lateral acceleration estimation unit configured to estimate a subsequent lateral acceleration of the vehicle; and a seat controller configured to control the seat. The seat has an occupant support adjustment portion including at least one of a first adjustment portion, a second adjustment portion, and a third adjustment portion. The seat controller calculates an adjustment amount of the occupant support adjustment portion and controls the occupant support adjustment portion in response to the calculated adjustment amount.
