Patent number: 11753000Abstract: When there are a plurality of routes to one parking space, automatic parking cannot be performed on a route with short parking time. A route candidate generation unit 301 changes a reference vehicle speed and a route shape, and searches for a route from a parking start position to a parking target position. The route passage time calculation unit 302 calculates, for each route candidate, the time required to pass through the route based on the reference vehicle speed and the length of the route. A state switching time calculation unit 303 calculates, for each route candidate, the time required for switching between forward and backward movements of a vehicle, and the time required to change steering to a predetermined steering angle in a state where the vehicle is stopped. A route selection processing unit 305 selects a specific route, for example, a route with short parking time, from a generated routes based on route passage time.Type: GrantFiled: January 8, 2019Date of Patent: September 12, 2023Assignee: Hitachi Astemo, Ltd.Inventors: Naoyuki Tashiro, Masato Imai, Takashi Tsutsui

Patent number: 11396288Abstract: In the invention, in automatic parking, a route from a parking start position to a target parking position is calculated prior to the start of parking. However, there are cases where an external environment recognition device cannot detect an obstacle at a distant or blind spot. In such a case, smooth parking is hindered when the vehicle is actually automatically parked. In the invention, in Step S1101, the vehicle is virtually moved from a parking start position 1201 in the direction of a turning position, and a turning position 1206 is calculated on a parking route 1205. In Step S1103, a preliminary route to a target parking position 1207 when the vehicle is turned back at the turning position 1206 is calculated. In the next Step S1104, it is determined whether the preliminary route can be generated, and when the preliminary route satisfies a predetermined condition, the route calculated by a candidate route calculation unit 501 is adopted as an automatic parking route.Type: GrantFiled: March 20, 2019Date of Patent: July 26, 2022Assignee: HITACHI ASTEMO, LTD.Inventors: Naoyuki Tashiro, Masashi Seimiya, Masato Imai, Shinya Kasai

Patent number: 11390272Abstract: Unfortunately, even when a new area, which cannot be recognized from the parking start position, is detected in the surrounding area as the vehicle travels on the parking route, the new area cannot be used effectively as the parking route. In step S304, when there is an area for extending the parking route in the newly detected area, the route is determined to be extensible. In step S305, it is determined whether the vehicle can be parked with one turnabout without extending the route, and when it is determined that the vehicle cannot be parked with one turnabout, the process proceeds to step S307 to perform the route extension process. When the posture of the vehicle at the turning point does not exceed a predetermined value in step S306, the process also proceeds to step S307.Type: GrantFiled: February 13, 2019Date of Patent: July 19, 2022Assignee: HITACHI ASTEMO, LTD.Inventors: Shinya Kasai, Masashi Seimiya, Masato Imai, Naoyuki Tashiro

Patent number: 11052895Abstract: When acceleration control is interrupted due to a lane change or the like, the engine speed is controlled from a high rotation speed to a low rotation speed, a variation in engine speed increases, and poor driver's driving performance is brought about. Furthermore, suppression of acceleration when there is a lane change possibility may rather cause the lane change and the driver feels discomfort. The vehicle control unit according to the present invention includes a target engine speed calculation unit which corrects a target engine speed to be reduced relative to a predetermined target engine speed when the acceleration/deceleration possibility determination unit determines that there is a deceleration possibility during acceleration to a target vehicle speed in automatic acceleration/deceleration control, and an engine control unit which controls an engine to have a target engine speed corrected by the target engine speed calculation unit.Type: GrantFiled: August 2, 2017Date of Patent: July 6, 2021Assignee: HITACHI AUTOMOTIVE SYSTEMS, LTD.Inventors: Naoyuki Tashiro, Takashi Okada
