In this embodiment, the controller is configured to transmit the stored display information to the projection device in response to an operation instruction of a user, so that the projection device respectively presents independent display images on the at least two projection areas.
In one particular example, the users may include, for example, a vehicle driver and a passenger; meanwhile, the operation command of the user may be, for example, a plurality of modes such as a voice input by the driver, a click of a corresponding virtual key on the center control screen of the vehicle by the driver, a pressing of a multifunctional key on the steering wheel by the driver, or a voice input by the passenger, a click of a corresponding virtual key on the center control screen of the passenger side, or the like. The operating instructions include a selection of an image stored within the controller.
In one specific example, two projection areas are included, which may be, for example, a projection area corresponding to the driver and a projection area corresponding to the co-driver, i.e., the projection device may provide separate display images for the driver and the user at the co-driver according to the display information transmitted by the controller, i.e., the display images provided by the projection device for the driver and the user at the co-driver may not be the same.

In yet another specific example, the display image presented by the projection device in the projection area corresponding to the co-driver may include a video image, a picture, or other entertainment information.

When the sight line direction of the driver is determined to be located on the copilot side, for example, when the driver observes road conditions or environmental information on the copilot side in the driving process, the controller adjusts the display information output to the projection device, for example, the controller does not output the display information corresponding to the display image displayed in the projection area corresponding to the copilot, or the controller adjusts the display information, so that the projection device reduces the size of the display image displayed in the projection area corresponding to the copilot, and therefore interference on the sight line of the driver is avoided.
In one particular example, the controller acquires the perception information from the eye tracking device in real time to determine the driver's gaze direction. When the change of the sight direction of the driver is determined, the controller adjusts the display information output to the projection equipment, so that the position of the display image projected by the projection equipment in the projection area corresponding to the driver is adjusted, the display image is more accurately attached to the real scene information outside the front windshield of the vehicle, the display image seen by the driver is ensured to be attached to the actual road, the parallax problem that eyeballs of the driver are located in different positions is solved, and the display effect of the head-up display system with the controller is improved.

if the output source of the operation instruction is the driver, judging whether the running speed of the vehicle meets a preset threshold value, if so, transmitting the stored display information to the projection equipment by the controller according to the operation instruction so that the projection equipment presents a corresponding display image in a projection area corresponding to the driver;
if the output source of the operation instruction is the passenger, the controller transmits the stored display information to the projection equipment according to the operation instruction, so that the projection equipment presents a corresponding display image in the projection area corresponding to the passenger.
In a specific example, the projection method of the head-up display system on the driver side is shown in fig. 5-6, and comprises the following steps:
s201, receiving an operation instruction of a user by a controller;
in a specific example, before step S201, the method further includes:
the controller judges the state of an ignition switch of the vehicle, and if the ignition switch is in an IGON state, the step S201 is carried out; if the ignition switch is in IGOFF, the head-up display system does not perform any display and operation.
S202, judging that an output source of the operation instruction is a driver or a passenger by the controller;
in a specific example, if the controller determines that the output source of the operation command is a passenger, the controller may display a corresponding display image, which may be a video image, a picture, or other entertainment information, according to the operation command of the passenger in the co-driver as long as the ignition switch is in the IGON state. If the controller determines that the output source of the operation command is the driver, step S203 is executed.
S203, judging whether the running speed of the vehicle meets a preset threshold value.
In one specific example, the preset threshold may be, for example, 0, that is, it is determined whether the vehicle is in a running state by determining whether the running speed of the vehicle satisfies the preset threshold, that is, whether the running speed is 0. When the driving speed of the vehicle is greater than 0, the projection device only presents driving related information (such as navigation, vehicle speed, fuel consumption, reverse video, graphics, GPS data, identification, and the like) in the projection area corresponding to the driver side, and the projection device is not allowed to present video images, pictures, or other entertainment information in the projection area corresponding to the driver side. When the traveling speed of the vehicle is not greater than 0, that is, the traveling speed of the vehicle satisfies a preset threshold, step S204 is performed.
And S204, the controller transmits the stored display information to the projection equipment according to the operation instruction, so that the projection equipment presents a corresponding display image in a projection area corresponding to the driver.
In a specific example, the vehicle is in a static state, and at this time, the driver may input an operation instruction in various manners, such as by voice input, or by clicking a corresponding virtual key on a center control screen of the vehicle or pressing a multi-function key on a steering wheel, so that the content of the display image displayed by the projection device in the projection area corresponding to the driver is selected, for example, a movie is played, and thus the driver may also view video images, pictures or other entertainment information.
According to the projection method, the output source of the operation instruction is judged in advance, so that the projection area corresponding to the driver always presents driving related information in the driving process of the vehicle, the phenomenon that the driver or passengers carry out misoperation to interfere normal driving of the driver is avoided, the driving safety of the vehicle is ensured, and traffic accidents are reduced; meanwhile, when the vehicle running speed meets a preset threshold value, a display image can be displayed in a projection area corresponding to the driver according to the operation instruction of the driver, so that the driver can relax the tight nerves during driving, the fatigue of the driver is relieved, and the driving experience of the driver is improved; moreover, the projection method can enable the passenger in the front passenger seat or the passenger in the rear passenger seat to select the corresponding operation instruction to watch the display image according to the preference of the passenger, and the riding experience of the passenger is improved.
In one possible implementation, the heads-up display system further includes an eye tracking device;
the projection method further includes:
