Patent number: 11472419Abstract: Provided is a vehicle control device capable of accurately estimating a self-vehicle location with a yaw angle error occurring when a vehicle starts to travel due to an initial phase shift between pulsed waveforms of left and right wheels when the vehicle starts to travel suppressed. The vehicle control device further estimates a direction of wheel rotation while the vehicle is at a stop. A yaw angle deviation when the vehicle starts to travel is estimated and corrected on the basis of a weighted average of discrete yaw angle values obtained immediately after the vehicle starts to travel from wheel speed sensors installed on left and right non-steered wheels of the vehicle. A yaw angle while the vehicle is at a stop and a yaw angle when the vehicle starts to travel are also estimated, and the direction of wheel rotation while the vehicle is at a stop is also estimated from a difference between the yaw angles. The yaw angle and coordinates are corrected on the basis of the estimation result.Type: GrantFiled: February 15, 2019Date of Patent: October 18, 2022Assignee: HITACHI ASTEMO, LTD.Inventors: Tomoyasu Sakaguchi, Takashi Tsutsui, Yoshiyuki Yoshida

Patent number: 11230284Abstract: The present driving assistance apparatus assists driving from a vehicle stop state in a predetermined area. The apparatus acquires outside world information from the surroundings of a vehicle, detects a place and position to which the vehicle can move, detects a position of the vehicle, calculates a movement route when the vehicle moves in a predetermined direction by automatic driving from a vehicle stop state in a predetermined area, and determines a safety confirmation position at which the driver can visually confirm a surrounding traveling environment on the movement route. The route is calculated based on the outside world information and the position of vehicle. The driving assistance apparatus reduces a speed of the vehicle to a predetermined speed or less so that the driver can visually confirm the surrounding traveling environment at the safety confirmation position.Type: GrantFiled: March 2, 2018Date of Patent: January 25, 2022Assignee: HITACHI ASTEMO, LTD.Inventors: Satoshi Matsuda, Yoshiyuki Yoshida

Patent number: 11155257Abstract: An automatic parking control device is capable of causing a vehicle to correctly reach the next frame without relying on normal parking route regeneration when a determination is made that the vehicle cannot reach the next frame under automatic parking vehicle control along a section route constituting a part of a parking route. When a determination is made whether the next frame is located on an extension of the current section route and the determination result shows that the next frame is located on the extension, the host vehicle travels further. When the determination is made whether the next frame is located on a remaining section of the current section route and the determination result shows that the next frame is located on the remaining section, the host vehicle decelerates earlier, thereby allowing the host vehicle to reach and come to a stop at the next frame.Type: GrantFiled: May 22, 2018Date of Patent: October 26, 2021Assignee: HITACHI AUTOMOTIVE SYSTEMS, LTD.Inventors: Munetoshi Tsuge, Yoshiyuki Yoshida, Masashi Seimiya, Keiichiro Hirakawa
