Patent number: 12084109Abstract: A vehicle control device includes a route processor that generates a route from a current location position to a target position. The target position remains constant. The vehicle control device further includes a steering pattern processor that generates a target steering angle, which is a target value of a steering angle for the route, and outputs steering angle information indicating the generated target steering angle. The vehicle control device further includes a steering angle processor that corrects the steering angle information such that a transition curve section of the route includes a steering angle increasing section where the steering angle is below the target steering angle and a steering angle decreasing section where the steering angle exceeds the target steering angle.

Patent number: 11935307Abstract: A vehicle control automatically distinguishes between a moving body and a stationary body, reduces user's operation process, and reduces burdens to shorten time for a parking process. Obstruction points are grouped so as to be divided between obstructions, coloring of moving and stationary bodies are changed for each obstruction, and it is determined whether there is an obstruction for which the coloring has not been changed. If there is an obstruction for which the coloring has not been changed, whether there is license plate information and whether the obstruction is a moving body or a stationary body are determined, and a moving body is changed to red and a stationary body to blue. A display device displays the obstruction information distinguished between stationary or moving objects, and a message to the user such as “obstruction stored” notifies the user of completion of the distinction of the obstruction types.Type: GrantFiled: December 14, 2018Date of Patent: March 19, 2024Assignee: HITACHI AUTOMOTIVE SYSTEMS, LTD.Inventors: Koichiro Ozaki, Takashi Tsutsui

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
