Abstract
A vehicle system includes a warning device and at least one electronic control unit. The at least one electronic control unit is configured to present a light stimulus to a driver, and determine whether the driver is facing forward, determine whether the driver holds a steering wheel, and cause the warning device to perform a first warning when it is determined that the driver is not facing forward while the light stimulus is being presented. The first warning is either the vibration or the sound. The at least one electronic control unit is configured to perform a second warning when it is determined that the driver does not hold the steering wheel before a predetermined time elapses after the first warning is started. The second warning includes the vibration and the sound.
Claims12
A vehicle system comprising:
- a warning device including
- at least one of a vibration generation device configured to generate a vibration and a sound output device configured to output a sound, and
- a display projection device configured to project a display on a display area of a head-up display provided in a vehicle;
- and
- at least one electronic control unit configured to
- present a light stimulus to a driver of the vehicle by using the head-up display when a change in a traffic environment is detected ahead of the vehicle, while the vehicle is performing autonomous driving,
- determine whether the driver is facing forward,
- determine whether the driver holds a steering wheel, and
- cause the warning device to
- perform a first warning, when it is determined that the driver is not facing forward while the light stimulus is being presented, the first warning being either the vibration generated by the vibration generation device or the sound output by the sound output device, and
- perform a second warning, when it is determined that the driver does not hold the steering wheel before a first predetermined time elapses after the first warning is started, the second warning including the vibration generated by the vibration generation device and the sound output by the sound output device.
A vehicle comprising:
- a sensor configured to detect a change in a traffic environment ahead of the vehicle;
- a head-up display including a display projection device, the display projection device being configured to present a light stimulus to a driver of the vehicle by projecting a display on a display area of the head-up display based on a detection result of the sensor;
- a warning device including at least one of a vibration generation device and a sound output device, the warning device configured to output at least one of a vibration generated by the vibration generation device and a sound output by the sound output device;
- and
- at least one electronic control unit configured to
- cause the display projection device to present the light stimulus,
- determine whether the driver is facing forward,
- cause the warning device to perform a first warning when it is determined that the driver is not facing forward while the light stimulus is being presented,
- determine whether the driver holds a steering wheel, and
- cause the warning device to perform a second warning, when it is determined that the driver does not hold the steering wheel before a first predetermined time elapses after the first warning is started, cause the warning device to perform a second warning, when it is determined that the driver does not hold the steering wheel before a first predetermined time elapses after the first warning is started, wherein the second warning:
- has a stimulus intensity higher than the stimulus intensity of the first warning, or
- is performed to stimulate a number of senses of the driver greater than a number of senses that the first warning is performed to stimulate.
