Abstract

A vehicle includes a vehicle platform that controls the vehicle and an autonomous driving kit that transmits commands for autonomous driving to the vehicle platform. The vehicle platform includes an accelerator pedal, a first emergency stop system that stops the vehicle in the event of an abnormality in the autonomous driving kit, and a second emergency stop system that stops the vehicle in the event of an emergency situation for the driver. The autonomous driving kit requires the vehicle platform to inhibit acceleration of the vehicle with the accelerator pedal while the second emergency stop system is activated. The vehicle platform prohibits acceleration of the vehicle using the accelerator pedal while the first emergency stop system is activated, regardless of whether or not there is a request from the autonomous driving kit.

Claims6

Dependent claims

A vehicle comprising:

a vehicle platform configured to control the vehicle;
and
an autonomous driving kit configured to transmit a command for autonomous driving to the vehicle platform, wherein:
the vehicle platform includes:
an accelerator pedal to be operated by a driver to accelerate the vehicle;
a first emergency stop system configured to stop the vehicle when an abnormality occurs in the autonomous driving kit;
and
a second emergency stop system configured to stop the vehicle when an emergency situation occurs for the driver;
the autonomous driving kit is configured to request the vehicle platform to accelerate the vehicle when the driver operates the accelerator pedal;
the autonomous driving kit is configured to request the vehicle platform to prohibit acceleration of the vehicle using the accelerator pedal while the second emergency stop system is operating;
and
the vehicle platform is configured to prohibit the acceleration of the vehicle using the accelerator pedal while the first emergency stop system is operating despite the vehicle platform receiving a request for acceleration from the autonomous driving kit.
