Vehicle Control Device
Provided is a vehicle control device capable of improving the riding comfort of a vehicle during parking control. A vehicle control device 10 includes: a distance measuring unit 14 that measures a distance between a position of a vehicle and a target stop position of the vehicle; and an acceleration setting unit 15 that sets an acceleration profile, which is a time change of a target value of acceleration during deceleration of the vehicle, according to the distance based on a jerk profile 15 a, which is a time change of a target value of jerk during deceleration of the vehicle.
1 . A vehicle control device, comprising:
a distance measuring unit that measures a distance between a position of a vehicle and a target stop position of the vehicle; and
an acceleration setting unit that sets an acceleration profile, which is a time change of a target value of acceleration during deceleration of the vehicle, according to the distance based on a jerk profile, which is a time change of a target value of jerk during deceleration of the vehicle.
2 . The vehicle control device according to claim 1 , wherein the jerk profile has a section in which the target value of the jerk is a constant positive value.
3 . The vehicle control device according to claim 2 , wherein the jerk profile has a section in which the target value of the jerk is a constant negative value.
4 . The vehicle control device according to claim 2 , wherein the jerk profile has a section in which the target value of the jerk is 0.
5 . The vehicle control device according to claim 3 , wherein an absolute value of the constant positive value and an absolute value of the constant negative value are equal to each other.
6 . The vehicle control device according to claim 1 , wherein the acceleration profile is continuous.
7 . The vehicle control device according to claim 1 , wherein the acceleration profile is continuous before and after start of braking.
8 . The vehicle control device according to claim 6 , further comprising:
a recognition unit that recognizes an obstacle around the vehicle; and
a stop position calculation unit that calculates a stop position for avoiding a collision with the obstacle,
wherein the acceleration setting unit sets a time of starting braking based on the stop position.
9 . The vehicle control device according to claim 6 , further comprising:
a route generation unit that generates a target route from a parking start position of the vehicle to the target stop position; and
a travel control unit that causes the vehicle to travel according to the acceleration profile and the target route,
wherein the travel control unit calculates an acceleration section, a constant speed section, and a deceleration section in the target route, and starts braking at a start position of the deceleration section.
10 . The vehicle control device according to claim 1 , wherein the acceleration setting unit includes a map that records a relationship between a parking start position of the vehicle, the target stop position, and the jerk profile, and sets the acceleration profile based on the map.
11 . The vehicle control device according to claim 1 , wherein the acceleration setting unit includes a computing unit that calculates the acceleration profile, and sets the acceleration profile calculated by the computing unit.
12 . The vehicle control device according to claim 1 , wherein the acceleration setting unit sets an emergency acceleration profile independent of the jerk profile in an emergency requiring a sudden stop.
