Abstract: A vehicle control apparatus includes at least one processor and at least one memory communicably coupled to the processor. The processor sets a target steering angle every predetermined cycle, on the basis of a curvature radius of a first arc passing through a current position of a vehicle, and controls a steering angle on the basis of the target steering angle. The processor sets the target steering angle by obtaining a second arc passing through the current position and tangent to a traveling direction of the vehicle, on the basis of a sum of minimum distances to the first arc from respective target points on a target path. The processor sets the target steering angle in a second cycle following a first cycle, before the vehicle reaches a position corresponding to the farthest one of the target points used for setting of the target steering angle in the first cycle.

Abstract: A vehicle control apparatus includes a processor. Before the vehicle passes through an inflection point of a curvature of a target trajectory, the processor sets a first reference point before the inflection point. After the vehicle passes through the inflection point, the processor sets a second reference point at a position where a second distance from a current position of the vehicle after the vehicle passes through the inflection point to the second reference point is longer than a first distance from a current position of the vehicle before the vehicle passes through the inflection point to the first reference point when compared under travel conditions identical in a vehicle speed, an acceleration rate, a deceleration rate, or a steering angle. The processor sets a target steering angle based on the curvature of an arc passing through the current position and the first reference point or the second reference point.

Abstract: A vehicle steering apparatus is configured to apply, to a steered wheel of a vehicle, a driving force for canceling a toe change amount caused by a road irregularity. The vehicle steering apparatus includes a road reaction force detector configured to detect a road reaction force received by a tire of the steered wheel, a toe adjustment actuator coupled to the steered wheel, and a controller configured to control a driving force of the toe adjustment actuator. The controller includes a toe change amount setter configured to set the toe change amount based on the road reaction force detected by the road reaction force detector, an operation amount calculator configured to calculate an actuator operation amount for canceling the toe change amount set by the toe change amount setter, and a driver configured to drive the toe adjustment actuator by the actuator operation amount calculated by the operation amount calculator.

Abstract: A control apparatus for a vehicle is provided. The vehicle includes driving motors provided for respective wheels. The driving motors each output driving torque for the vehicle and output regenerative torque. The control apparatus includes: one or more processors; and one or more memories communicably coupled to the one or more processors. The processors predict an output increased state ahead in a direction of travel of the vehicle. The output increased state causes output torque of any of the driving motors to be larger than a rated output. On the condition that the output increased state is predicted, the processors limit the driving torque and the regenerative torque of a relevant one of the driving motors expected to produce an output larger than the rated output in the output increased state, to under the rated output, until the output increased state occurs.

Abstract: A front-rear wheel driving force distribution device includes a center differential and a limited slip differential. The limited slip differential includes a first clutch, a second clutch, a first piston, a second piston, and a one-way clutch provided between the first clutch and a rear propeller shaft. If the second clutch is engaged by the second piston, the propeller shaft on the rear side rotates at increased speed as compared with a case where the first clutch is engaged by the first piston. The one-way clutch couples the first clutch and the rear propeller shaft if a number of rotations of the first clutch is same as or higher than a number of rotations of the rear propeller shaft, and idles if the number of rotations of the first clutch is lower than the number of rotations of the rear propeller shaft.

Abstract: A driving assistance apparatus assists driving of a first vehicle. The driving assistance apparatus includes at least one processor and at least one memory communicably coupled to the at least one processor. The at least one processor acquires information on a traveling state of the first vehicle and information on a surrounding environment of the first vehicle, determines a factor that provokes tailgating by comparing the information on the traveling state of the first vehicle with accumulated data on traveling states of second vehicles in a driving condition belonging to the same category as a driving condition of the first vehicle, and presents feedback information about a driving action of a driver who drives the first vehicle on the basis of the factor that provokes the tailgating.
