Embodiment Construction
[0019] Embodiments of the present invention will be described below with reference to the drawings. In the description of the drawings, the same reference numerals are assigned to the same parts.
[0020] [Ride Control Device]
[0021] refer to figure 1 An example of the vehicle layout of the travel control device according to the embodiment will be described. The vehicle 1 (hereinafter referred to as "the vehicle") is equipped with brake lamps 4a, 4b, an ignition switch 18 for instructing the start and stop of the driving force generating device including the engine and the motor, and detecting an obstacle approaching the front PD of the vehicle 1. The front obstacle detection sensors 13a to 13d, 19e, the rear obstacle detection sensors 13e to 13h that detect obstacles approaching the rear of the host vehicle 1, and the side obstacle detection sensors that detect obstacles approaching the sides of the host vehicle 1 The sensors 19a to 19d, the driving force generating devi...

The travel control device includes: rear obstacle detection sensors (13e-13h); side obstacle detection sensors (19a-19d); rear movement preparation detection unit (9); and the control unit, the distance between the obstacle (61) and the obstacle (61) detected by the rear obstacle detection sensors (13e~13h) is below the first risk or based on the side obstacle detection sensor ( 19a to 19d) When the parameter of the detected distance from the obstacle (61) is equal to or less than the second risk, the warning unit is controlled to give a warning. When it is detected that the host vehicle (1) is preparing to move backward, and the parameter based on the distance to the obstacle detected by the side obstacle detection sensors (19a-19d) is greater than the second risk, the control unit starts from The side obstacle detection sensors ( 19 a to 19 d ) increase the first warning threshold until the hold time elapses after the obstacle is no longer detected.
Description
technical field [0001] The present invention relates to a travel control device and a travel control method. Background technique [0002] Conventionally, there is known a technique for detecting an obstacle approaching the periphery of the vehicle using an obstacle sensor mounted on the vehicle (for example, refer to Patent Document 1). [0003] In Patent Document 1, an ultrasonic sensor whose detection area is the rear of the vehicle and an ultrasonic sensor whose detection area is the rear side of the vehicle are mounted on the rear portion of the vehicle. Ultrasonic sensors that use the rear side of the vehicle as the detection area have a sensing area that can detect obstacles as far as the rear. In contrast, ultrasonic sensors that use the rear of the vehicle as the detection area can only detect obstacles near the vehicle. . As a result, there is a non-sensing area in which obstacles cannot be detected at a distance directly behind the host vehicle. [0004] Patent...
