Parking assist apparatus
A parking assist apparatus that causes a vehicle to be parked in a target parking position generates a traveling route of a vehicle M from a parking travel start position P 0 to a target parking position P 2 (S 12 ); generates a plurality of speed patterns having different speeds when the vehicle travels on the traveling route (S 14 ); selects a target speed pattern from the plurality of speed patterns based on information of an object around the traveling route (S 18 ); and controls the traveling of the vehicle M based on the target speed pattern (S 24 ).
1. A parking assist apparatus that causes a vehicle to travel along a traveling route from a parking travel start position to a target parking position and performs a parking assist, comprising:
a speed pattern generation unit that generates a plurality of speed patterns having different speeds at the time of traveling on the traveling route;
an information acquisition unit that acquires at least information of a distance between the traveling route and an object, information of the number of objects, and information on whether or not the object is moving, as the information of the object existing around the traveling route;
a selection unit that selects a target speed pattern from the plurality of speed patterns based on the information of the object; and
a parking control unit that controls traveling of the vehicle based on the target speed pattern.
2. The parking assist apparatus according to claim 1 ,
wherein the speed pattern generation unit generates a plurality of speed patterns including at least a standard speed pattern in which the vehicle is accelerated, decelerated, and then stopped, and a low speed pattern in which the vehicle is accelerated and decelerated to a preset first speed, and the vehicle is stopped after keeping the first speed.
3. The parking assist apparatus according to claim 2 ,
wherein, in a case where the object does not exist within a preset first distance from the traveling route, the selection unit selects the standard speed pattern as the target speed pattern, and
wherein, in a case where the object exists within the first distance from the traveling route, the selection unit selects the low speed pattern as the target speed pattern.
4. The parking assist apparatus according to claim 2 ,
wherein, in a case where the number of objects existing within a preset second distance from the traveling route is not equal to or larger than a preset first threshold value, the selection unit selects the standard speed pattern as the target speed pattern, and
wherein, in a case where the number of objects existing within the second distance from the traveling route is equal to or larger than the first threshold value, the selection unit selects the low speed pattern as the target speed pattern.
5. The parking assist apparatus according to claim 2 ,
wherein, in a case where a moving object does not exist within a preset third distance from the traveling route, the selection unit selects the standard speed pattern as the target speed pattern, and
wherein, in a case where the moving object exists within the third distance from the traveling route, the selection unit selects the low speed pattern as the target speed pattern.
6. The parking assist apparatus according to claim 2 , further comprising:
a notification unit that notifies a driver of the vehicle that a low speed traveling control is performed, in a case where the low speed pattern is selected as the target speed pattern by the selection unit.
