  • Patent number: 11935307
    Abstract: 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.

  • Publication number: 20240042994
    Abstract: The present disclosure provides a vehicle control device capable of improving safety of a vehicle. A vehicle control device according to the present disclosure includes a target speed calculation unit 126 that calculates a target speed of a vehicle. The target speed calculation unit 126 includes a first speed calculation unit 126a, a second speed calculation unit 126b, and a target speed setting unit 126f. The first speed calculation unit 126a calculates, by using a friction coefficient of a road surface and a route length of a target route to an outer edge of a sensing range of an external environment sensor of the vehicle, a first speed at which the vehicle can stop at a stop position before the outer edge. The second speed calculation unit 126b calculates, by using a curvature radius of the target route of the vehicle and the friction coefficient, a second speed at which the vehicle can follow the target route.

  • Patent number: 11753000
    Abstract: 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.

  • Patent number: 11472419
    Abstract: 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.

  • Patent number: 11383723
    Abstract: Provided is a vehicle control device capable of suppressing a yaw angle error at startup due to an initial phase shift of pulse waveforms of right and left wheels at the startup and precisely estimating a vehicle position. A yaw angle displacement amount of the vehicle is corrected in the direction of reducing an error in the yaw angle displacement amount at the estimation start point with respect to a reference direction in which the vehicle is to travel depending on output of a pulse waveform of a wheel speed sensor provided in right and left non-steering wheels of the vehicle immediately after the startup. Specifically, a range of an estimation error in a traveling direction at the startup is limited by two steps of correction at the startup.
