Problems solved by technology

If the vehicle speed is uniformly set, there is a possibility that it may take an inconveniently long time to drive to the target position, or that sufficient vehicle speed cannot be obtained even if the driver tries to increase the speed, thereby degrading the controllability

Embodiment Construction

[0030] In the following description, the present invention will be described more specifically based on representative examples.

[0031] As an example, the driving assist device according to the present invention will be described below with reference to a parking assist device. figure 1 A block diagram showing the architecture of the parking assistance device 100 according to an exemplary embodiment of the present invention. The parking assist device 100 has an automatic steering device 20, and is controlled by a parking assist ECU 1 as a control device. The parking assist ECU 1 is composed of a CPU, a ROM, a RAM, an input signal circuit, an output signal circuit, a power supply circuit, and the like. Also, the parking assist ECU 1 has an image processing section 10 that processes images captured by a rear camera 32 described later, and a steering control section 11 that controls the automatic steering device 20 . The image processing section 10 and the steering control se...

Abstract

Disclosed is an auxiliary device for driving vehicle, which can guide the vehicle traveling at a correct speed according to the way. A valarm, which is used to tell the driver that it is overspeed, in variation transition area is set below that in fixation transition area. Set a lower valarm before entering into the variation transition area. Thus, in the variation transition area, the vehicle speed can decrease adequately to complete the set steering value. And in the fixation transition area, the vehicle speed increases to shorten running time.

Description

technical field [0001] The present invention relates to a vehicle driving assist device and method for determining a driving trajectory to a target position and assisting in driving a vehicle so that the vehicle advances along the driving trajectory. Background technique [0002] A related art technique for guiding a vehicle to a target position by using automatic steering, steering commands, etc., is disclosed, for example, in Japanese Patent Application Laid-Open Publication No. 10-278825. In this related art, a reference amount of operation of a brake pedal is preset to adjust a vehicle speed according to a reaction speed of a steering actuator during automatic steering. The deviation between the reference amount of manipulation and the actual amount of manipulation caused by the driver is calculated and indicated to the driver. Thus, the vehicle speed can be prevented from becoming too high or too low, so that appropriate automatic parking control is possible. [0003]...
