The vehicle hand brake state detection means may judge whether the vehicle is stopped or not, for example, by detecting whether the vehicle hand brake is in a pulled up state.

By way of the above-described configuration, the driver may switch a play mode of the vehicle-mounted entertainment device in an easy manner according to his own will whilst ensuring safe drive, thereby making full use of the time when the vehicle is stopped for entertainment activities.

Preferably, the first action of the driver is a foot action. Correspondingly, the first action detecting unit 12 may be a driver’s foot action detection means. The driver’s foot action detection means may send out a first switching signal when detecting the driver’s foot action.

More preferably, the first action is an action of the driver’s foot stepping on the brake pedal. Correspondingly, the first action detecting unit 12 may include a brake pedal sensor. The brake pedal sensor may be a displacement sensor, a pressure sensor or any other suitable sensor adapted to detect a driver’s foot action. The brake pedal sensor is configured to detect an action of the driver’s foot stepping on the brake pedal and may send out a first switching signal upon sensing the action of the driver’s foot stepping on the brake pedal.

More preferably, the first action is an action of the driver’s foot stepping on the brake pedal for predetermined times. The brake pedal sensor is configured to detect an action of the driver’s foot stepping on the brake pedal for predetermined times and may send out the first switching signal upon sensing the action of the driver’s foot stepping on the brake pedal for predetermined times. Preferably, the number of times is two. The number of times may also be one, three or more.

By switching a play mode of the vehicle-mounted entertainment device according to the driver’s foot action, especially the action of foot stepping on the brake pedal for predetermined times, the play mode may be switched in the most natural and simple manner without distracting the driver’s attention, and moreover, there is no need to make excessive modifications to the vehicle so that the cost is inexpensive.

Preferably, the switching system 1 of the vehicle-mounted entertainment device further comprises a second action detecting unit 14. The second action detecting unit 14 is configured to detect a second action of the driver and may generate a second switching signal when the second action of the driver is detected. The controller 13 is further configured to: send an instruction to turn off the vehicle-mounted entertainment device or switch it to the audio mode when the second switching signal is received (i.e. the second action detecting unit 14 detects the second action of the driver) and the vehicle-mounted entertainment device is in the text and/or image mode.

Preferably, the second action is a driver’s foot action. More preferably, the second action is an action of the driver foot stepping on the accelerator pedal, and correspondingly, the second action detecting unit includes an accelerator pedal sensor which is configured to detect an action of the driver’s foot stepping on the accelerator pedal and may generate the second switching signal upon detecting the action of the driver’s foot stepping on the accelerator pedal.

By way of this configuration, the driver may simply and naturally turn off the vehicle-mounted entertainment device or switch it to the audio mode by foot stepping on the accelerator. The operation thereof is simple without distracting the driver’s attention, and there is no need to make excessive modifications to the vehicle so that the cost is inexpensive.

Those skilled in the art will appreciate that the first action and the second action of the driver are not limited to the actions of the foot stepping on the brake pedal and the foot stepping on the accelerator pedal. For example, the first action and/or the second action of the driver may also be other foot actions of stepping on the clutch pedal or other components. It may also be appreciated by those skilled in the art that the first action and/or the second action of the driver are not limited to a foot action. The first action and/or the second action may also be a hand action. Correspondingly, the first action detecting unit 12 and/or the second action detecting unit 14 may be a touch portion. The touch portion may be a touch button or a similar member located on, for example, a steering wheel, a vehicle-mounted entertainment device or a console, or the like, which is configured to detect a hand action of the driver and may send out a first switching signal and/or a second switching signal according to the detected hand action. The first action and/or the second action may also be a voice action. Correspondingly, the first action detecting unit 12 and/or the second action detecting unit 14 may be a voice recognition unit. The voice recognition unit is configured to detect a vocal instruction of the driver and may send out a first switching signal and/or a second switching signal according to the detected vocal instruction.

Preferably, the controller 13 is configured such that, the controller 13 sends an instruction to turn off the vehicle-mounted entertainment device or to switch it to the audio mode when the second action detecting unit 14 detects the second action of the driver (i.e., generating a second switching signal) and the vehicle state judgment unit 11 judges that the vehicle is not in a stopped state (i.e., generating a vehicle travel signal) and the vehicle-mounted entertainment device is in the text and/or image mode.

According to such configuration, when the switching system 1 of the vehicle-mounted entertainment device switches a play mode of the vehicle-mounted entertainment device according to the second switching signal, it is necessary to further confirm that the vehicle is in a travel state, thereby avoiding that the foot accidentally touches the accelerator pedal in a parking state to cause improper switching.

The switching method for a vehicle-mounted entertainment device according to the present disclosure will be described below. For the sake of brevity, the following method may omit what has been described above. However, the switching method for a vehicle-mounted entertainment device according to the present disclosure may use any of the features in the switching system for a vehicle-mounted entertainment device described above, separately or by combination in any manner.

In general, when the vehicle is in a stopped state, when the driver makes a first action, especially a first foot action, more especially an action of foot stepping on the brake pedal for predetermined times, the vehicle-mounted entertainment device switches to a text and/or image mode, particularly switching from a sound mode to the text and/or image mode.

In one preferred embodiment, as shown in FIG. 2, in the step S1, the first action of the driver is detected. Preferably, the detection of the first action of the driver may be implemented by the above-described first action detecting unit 12. Preferably, the first action is a driver’s foot action. More preferably, the first action is an action of the driver’s foot stepping on the brake pedal. More preferably, the first action is an action of the driver’s foot stepping on the brake pedal for predetermined times. Further preferably, the first action is an action of the driver’s foot stepping on the brake pedal twice. The number of predetermined times may also be one, three or more. Preferably, the action of the driver’s foot stepping on the brake pedal for predetermined times may be such that the foot briefly steps on the brake pedal lightly for predetermined times. As described above, the first action may also be, for example, an action of the driver’s foot stepping on other members, or an action of the driver’s hand pressing the touch portion or the driver’s vocal instruction.

In one preferred embodiment, as shown in FIG. 2, in the step S2, it is judged whether the vehicle is in a stopped state. Preferably, the judgment of whether the vehicle is in a stopped state may be implemented by the above-described vehicle state judgment unit 11.

In one preferred embodiment, as shown in FIG. 2, in the step S31, it is judged whether the first action of the driver is detected and the vehicle is in a stopped state. If the judgment result in the step S31 is “YES” , the vehicle-mounted entertainment device is switched to the text and/or image mode in the step S32. The step 31 and the step S32 may be implemented, for example, by the above-described controller 13.

Please note that, the above-described steps S1 and S2 do not have to be performed in the sequence listed above, but may be performed reversely or simultaneously. For example, after the driver steps on the brake pedal to stop the vehicle, the step S2 may firstly be performed to confirm whether the vehicle is in a stopped state, and then step S1 is performed to detect whether the driver makes the first action.

According to this method, the driver may easily and naturally effectuate switching the play mode of the vehicle-mounted entertainment device by foot stepping on the brake pedal in a specific manner. This method avoids the problem that the previous switching methods may distract the driver’s attention or the cost is too high, so that the driver can switch the play mode of the vehicle-mounted entertainment device according to his own will even within a transitory parking time.

Preferably, switching the vehicle-mounted entertainment device to a text and/or image mode includes switching the vehicle-mounted entertainment device from an audio mode to the text and/or image mode, or from an off mode to the text and/or image mode.

In one preferred embodiment, as shown in FIG. 3, the switching method for a vehicle-mounted entertainment device according to the present disclosure includes the step S4 and the steps S51 and S52.

Preferably, in the step S4, the second action of the driver is detected. Preferably, the second action is a driver’s foot action. More preferably, the second action is an action of the driver’s foot stepping on the accelerator pedal. Those skilled in the art may appreciate that the second action may also be an action of the driver’s foot stepping on other components, or an action of the driver’s hand pressing the touch portion or the driver’s vocal instruction.

Preferably, in the step S51, it is judged whether the second action of the driver is detected and the vehicle-mounted entertainment device is in the text and/or image mode. When the judgment result in the step S51 is “YES” , the step S52 is performed, in which the vehicle-mounted entertainment device is turned off or switched to the audio mode. By this method, the driver may turn off the vehicle-mounted entertainment device or switch it to the audio mode whilst driving by simply stepping on the accelerator pedal.

More preferably, in another preferred embodiment, as shown in Fig. 4, the step S51 is replaced with the step S51'. In the step S51', it is judged whether the second action of the driver is detected and the vehicle is not in the stopped state and the vehicle-mounted entertainment device is in the text and/or image mode. When the judgment result in the step S51'is YES, the above-described step S52 is performed. By this method, it is also possible to prevent accidental switching of the vehicle-mounted entertainment device by accidentally stepping on the accelerator pedal during parking.

The above-described step S4 and step S51 (or S51') and S52 may be used alone, and may also be used in combination with the above-described steps S1, S2 and S31 and S32.

The present disclosure also includes a vehicle-mounted entertainment device. The vehicle-mounted entertainment device comprises a screen for displaying text and/or images. The vehicle-mounted entertainment device may be connected to a controller of the vehicle. The controller of the vehicle functions as the controller 13 as described above.
