Abstract

A VP carries out vehicle control in accordance with an instruction from an ADK. A vehicle control interface interfaces between the VP and the ADK. The vehicle control interface receives from the ADK, a power supply mode request which is an instruction for controlling a power supply mode of the VP. The power supply mode includes a sleep mode in which a vehicle is in a Ready OFF state, a driving mode in which the vehicle is in a Ready ON state, and a wake mode in which the vehicle control interface is on.

First claim

What is claimed is:

1. A vehicle on which an autonomous driving system that creates a driving plan is mountable, the vehicle comprising:
a vehicle platform that carries out vehicle control in accordance with an instruction from the autonomous driving system; and
a vehicle control interface box installed in the vehicle and separate from the autonomous driving system that interfaces between the vehicle platform and the autonomous driving system, the autonomous driving system being externally attachable to and removable from the vehicle, wherein
the vehicle control interface box includes
a processor, and
a memory that stores a program executable by the processor, the processor
receives from the autonomous driving system, an instruction for travelling the vehicle in accordance with the driving plan created by the autonomous driving system, and transmits to the autonomous driving system, signals that indicate states of the vehicle,
receives a power supply mode request from the autonomous driving system, the power supply mode request being an instruction for controlling a power supply mode of the vehicle platform,
transmits a power supply mode status to the autonomous driving system, the power supply mode status indicating a status of the power supply mode of the vehicle platform, and
performs processing in accordance with the receiver power supply mode request in accordance with the program, and

the power supply mode includes
a sleep mode in which the vehicle is in a Ready OFF state,
a driving mode in which the vehicle is in a Ready ON state, and
a wake mode in which the vehicle control interface box is on,

the vehicle platform includes a high-voltage battery and an auxiliary battery,
the sleep mode is a mode in which the vehicle control interface box and each system of the vehicle platform is not on,
the driving mode is a mode in which power is fed from the high-voltage battery to each system of the vehicle platform, and
the wake mode is a mode in which the vehicle control interface box is activated by power feed from the auxiliary battery and is on by power feed from the auxiliary battery, and in which power is not fed from the high-voltage battery.

2. The vehicle according to claim 1 , wherein
the processor is configured to refuse to act on a next power supply mode request for a certain time period after reception of the power supply mode request from the autonomous driving system.

3. The vehicle according to claim 2 , wherein
the certain time period is substantially 4000 milliseconds.

4. The vehicle according to claim 1 , wherein
the processor transmits the sleep mode as the power supply mode status to the autonomous driving system for a prescribed time period after sleep processing is performed in accordance with a request for the sleep mode, and thereafter shuts down.

5. The vehicle according to claim 4 , wherein
the prescribed time period is substantially 3000 milliseconds.

6. A vehicle control interface box that interfaces between an autonomous driving system that creates a driving plan and a vehicle platform that carries out vehicle control in accordance with an instruction from the autonomous driving system, the vehicle control interface box comprising:
a processor; and
a memory that stores a program executable by the processor, wherein
the processor
receives from the autonomous driving system, an instruction for travelling the vehicle in accordance with the driving plan created by the autonomous driving system, and transmits to the autonomous driving system, signals that indicate states of the vehicle,
receives a power supply mode request from the autonomous driving system, the power supply mode request being an instruction for controlling a power supply mode of the vehicle platform,
transmits a power supply mode status to the autonomous driving system, the power supply mode status indicating a status of the power supply mode of the vehicle platform, and
performs processing in accordance with the received power supply mode request in accordance with the program, and

the power supply mode includes
a sleep mode in which a vehicle is in a Ready OFF state,
a driving mode in which the vehicle is in a Ready ON state, and
a wake mode in which the vehicle control interface box is on,

wherein the vehicle platform includes a high-voltage battery and an auxiliary battery,
the sleep mode is a mode in which the vehicle control interface box and each system of the vehicle platform is not on,
the driving mode is a mode in which power is fed from the high-voltage battery to each system of the vehicle platform,
the wake mode is a mode in which the vehicle control interface box is activated by power feed from the auxiliary battery and is on by power feed from the auxiliary battery, and in which power is not fed from the high-voltage battery, and
the vehicle control interface box is installed in the vehicle and separate from the autonomous driving system.

7. The vehicle control interface box according to claim 6 , wherein
the processor is configured to refuse to act on a next power supply mode request for a certain time period after reception of the power supply mode request from the autonomous driving system.

8. The vehicle control interface box according to claim 7 , wherein
the certain time period is substantially 4000 milliseconds.

9. The vehicle control interface box according to claim 6 , wherein
the processor transmits the sleep mode as the power supply mode status to the autonomous driving system for a prescribed time period after the processor performs sleep processing in accordance with a request for the sleep mode, and thereafter shuts down the vehicle control interface box.

10. The vehicle control interface box according to claim 9 , wherein
the prescribed time period is substantially 3000 milliseconds.

11. An autonomous driving vehicle comprising:
an autonomous driving system that is externally attachable to and removable from the vehicle and that creates a driving plan;
a vehicle platform that carries out vehicle control in accordance with an instruction from the autonomous driving system; and
a vehicle control interface box that interfaces between the vehicle platform and the autonomous driving system, wherein
the vehicle control interface box includes
a processor, and
a memory that stores a program executable by the processor, the processor
receives from the autonomous driving system, an instruction for travelling the vehicle in accordance with the driving plan created by the autonomous driving system, and transmits to the autonomous driving system, signals that indicate states of the vehicle,
receives a power supply mode request from the autonomous driving system, the power supply mode request being an instruction for controlling a power supply mode of the vehicle platform,
transmits a power supply mode status to the autonomous driving system, the power supply mode status indicating a status of the power supply mode of the vehicle platform, and
performs processing in accordance with the received power supply mode request in accordance with the program, and
