Vehicle controller
View Patent ↗A vehicle controller includes a camera unit that detects driving conditions of a preceding vehicle; a re-acceleration determiner that determines based on the driving conditions of the preceding vehicle whether or not a re-acceleration state in which the preceding vehicle decelerates and then accelerates occurs; and a rotation controller that, if it is determined that the vehicle is in a re-acceleration state, maintains the engine speed of the engine not less than a lower limit.
1. A vehicle controller comprising:
a sensor that detects a driving condition of a preceding vehicle;
a re-acceleration determiner configured to determine, based on the driving condition of the preceding vehicle and the subject vehicle, whether or not a re-acceleration state where the preceding vehicle decelerates and then accelerates occurs, wherein the re-acceleration determiner determines that the preceding vehicle is in the re-acceleration state when the preceding vehicle is accelerated from a state in which both the preceding vehicle and the subject vehicle are decelerating; and
a rotation controller that, when the re-acceleration determiner determines that the preceding vehicle is in the re-acceleration state, maintains a rotational speed of an engine not less than a lower limit, wherein the lower limit is higher than an idling speed.
2. The vehicle controller according to claim 1 , further comprising:
an electric motor connected to the engine,
wherein the rotation controller drives the electric motor to maintain the rotational speed of the engine not less than a lower limit.
3. The vehicle controller according to claim 2 ,
wherein the rotation controller shuts down fuel supply to the engine to maintain the rotational speed of the engine not less than a lower limit.
4. The vehicle controller according to claim 1 ,
wherein the rotation controller supplies fuel to the engine to maintain the rotational speed of the engine not less than a lower limit.
5. The vehicle controller according to claim 1 ,
wherein, when a driver of the vehicle equipped with the vehicle controller performs a brake operation, the rotation controller disables a lower-limit maintenance control that maintains the rotational speed of the engine not less than a lower limit.
6. The vehicle controller according to claim 2 ,
wherein, when a driver of the vehicle equipped with the vehicle controller performs a brake operation, the rotation controller disables a lower-limit maintenance control that maintains the rotational speed of the engine not less than a lower limit.
7. The vehicle controller according to claim 3 ,
wherein, when a driver of the vehicle equipped with the vehicle controller performs a brake operation, the rotation controller disables a lower-limit maintenance control that maintains the rotational speed of the engine not less than a lower limit.
8. The vehicle controller according to claim 4 ,
wherein, when a driver of the vehicle equipped with the vehicle controller performs a brake operation, the rotation controller disables a lower-limit maintenance control that maintains the rotational speed of the engine not less than a lower limit.
