Abstract
When the preceding vehicle is stopped in front of the traffic light, the lighting color of the traffic light is “green”, the other vehicle is not stopped immediately before the preceding vehicle, the direction indicating light of the preceding vehicle is off, and the distance between the host vehicle and the preceding vehicle at the time when the preceding vehicle is detected exceeds a threshold value, the processor controls the predetermined device so that the host vehicle travels at a constant speed, or controls the predetermined device of the host vehicle so that the speed of the host vehicle decreases in the second mode that is slower than the first mode.
Claims5
A drive assist device comprising:
- a vehicle sensor configured to acquire information on a host vehicle and information on an object located ahead of the host vehicle;
- and
- a processor configured to execute a speed adjustment process for controlling a predetermined device of the host vehicle such that a vehicle-to-vehicle distance between the host vehicle and a preceding vehicle that is another vehicle located immediately ahead of the host vehicle agrees with a predetermined target value, the processor being configured to start, as the speed adjustment process, a first process for controlling the predetermined device such that the host vehicle decelerates in a predetermined first mode when a stopped preceding vehicle is detected, wherein
- the processor is configured to, when
- the preceding vehicle is at a standstill behind a traffic light,
- a lighting color of the traffic light is green,
- no other vehicle is at a standstill immediately ahead of the preceding vehicle,
- a direction indication light of the preceding vehicle is off, and
- a distance between the host vehicle and the preceding vehicle at a time when the preceding vehicle is detected exceeds a threshold value,
- start a second process as an alternative to the first process, the second process including a process of controlling the predetermined device such that the host vehicle travels at a constant speed, or a process of controlling the predetermined device such that a speed of the host vehicle decreases more slowly in a second mode than in the first mode.
