Vehicle display control device, vehicle display device, vehicle display control method, and non-transitory storage medium

A vehicle display control method, executed by a processor, for controlling a vehicle display device configured to display an image at a display region so as to be superimposed on a portion of a view ahead of a host vehicle, the vehicle display control method comprising:

• detecting a preceding vehicle traveling at a vehicle front side relative to the host vehicle,
• causing an image that includes a plurality of inter-vehicle marker objects from the host vehicle side toward the preceding vehicle side to be displayed at the display region when the preceding vehicle has been detected, the image including the plurality of inter-vehicle markers being displayed more faintly than other images being displayed at the display region,
• detecting whether or not the host vehicle is being controlled by adaptive cruise control, and detecting whether or not the preceding vehicle is a target for following-travel control of the host vehicle when the preceding vehicle has been detected, and
• when it has been detected that the host vehicle is being controlled by adaptive cruise control and the preceding vehicle is the target for following-travel control of the host vehicle, implementing sequential emphasis display by raising a brightness of the plurality of inter-vehicle marker objects in sequence from the host vehicle side toward the preceding vehicle side for respective fixed periods of time.

A non-transitory storage medium storing a program executable by a processor to perform vehicle display control processing for controlling a vehicle display device configured to display an image at a display region so as to be superimposed on a portion of a view ahead of a host vehicle, the vehicle display control processing comprising:

• detecting a preceding vehicle traveling at a vehicle front side relative to the host vehicle,
• causing an image that includes a plurality of inter-vehicle marker objects from the host vehicle side toward the preceding vehicle side to be displayed at the display region when the preceding vehicle has been detected, the image including the plurality of inter-vehicle markers being displayed more faintly than other images being displayed at the display region,
• detecting whether or not the host vehicle is being controlled by adaptive cruise control, and detecting whether or not the preceding vehicle is a target for following-travel control of the host vehicle when the preceding vehicle has been detected, and
• when it has been detected that the host vehicle is being controlled by adaptive cruise control and the preceding vehicle is the target for following-travel control of the host vehicle, implementing sequential emphasis display by raising a brightness of the plurality of inter-vehicle marker objects in sequence from the host vehicle side toward the preceding vehicle side for respective fixed periods of time.
