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...

A travel control device, having: rear direction obstacle detection sensors (13e-13h); side direction obstacle detection sensors (19a-19d); a rear direction movement preparation detection unit (9); a warning unit that provides a warning about obstacles detected by the sensors (19a-19h); and a control unit that controls the warning unit such that a warning is provided if the distance to an obstacle (61) detected by the rear direction obstacle detection sensors (13e-13h) is no greater than a first risk value or if a parameter based on the distance to the obstacle (61) detected by the side direction obstacle detection sensors (19a-19d) is no greater than a second risk value. If preparation by a vehicle (1) to move in the rear direction is detected, and if the parameter based on the distance to the obstacle detected by the side direction obstacle detection sensors (19a-19d) is greater than the second risk value, the control unit increases a first warning threshold value, between when the side direction obstacle detection sensors (19a-19d) can no longer detect the obstacle until a holding period has passed.
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...
