The terminology used herein in the description of the present invention is only for the purpose of describing specific embodiments, and is not intended to limit the present invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The driving mode switching system and method will be described below with reference to a car. However, it will be appreciated that the invention is equally applicable to any vehicle suitable for personal transportation, such as trucks, buses and the like. The invention is particularly applicable to vehicles intended to be driven on public roads.

Referring to FIG. 1 , a vehicle 10 according to an embodiment of the present invention is equipped with a vehicle driving mode switching system 100 for switching between an automatic driving mode and a manual driving mode of the vehicle 10 . The vehicle 10 also includes a navigation module 500 , a steering wheel 600 and an accelerator pedal 700 . The automatic driving module 200 and the manual driving module 300 are respectively connected to the navigation module 500 . The manual driving module 300 is connected with a steering wheel 600 and an accelerator pedal 700 .

When the manual driving module 300 of the vehicle 10 is working, the vehicle 10 operates in the manual driving mode. The manual driving mode is a traditional manual driving mode, and the vehicle 10 can be driven by the driver manipulating at least the steering wheel 600 and the accelerator pedal 700 . Certainly, in the manual driving mode, the vehicle 10 also needs other operating devices to cooperate in driving, for example, a brake pedal, a gear lever, a clutch, and a horn.

When the automatic driving module 200 of the vehicle 10 works, the vehicle 10 operates in the automatic driving mode. Autopilot mode is a vehicle autonomous driving mode, which can combine existing sensing technology, Adaptive Cruise Control (ACC), Lane Keeping Assist (LKA), Electric Power Steering (EPAS), Active Front Wheel Steering, Parking Assistance, anti-lock braking (ABS), traction control, electronic stability control (ESC), blind spot detection, global positioning system (GPS) and map database, vehicle-to-vehicle communication, etc. to achieve semi-autonomous driving of vehicles (requiring fewer drivers intervention) or fully autonomous driving (no driver intervention required). Autonomous vehicles offer the advantages of safer driving, improved mobility, and better coordination between vehicles.

The driving mode switching module 130 includes a trigger judging module 135 . The prompt module 150 is connected to the driving mode switching module 130 , the automatic driving module 200 and the manual driving module 300 . The steering wheel pressure sensor 160 is disposed on the steering wheel 600 . The accelerator pressure sensor 170 is arranged on the accelerator pedal 700 .

The driving mode switching module 130 can recognize the pressure sensing signals from the steering wheel pressure sensor 160 and the accelerator pressure sensor 170 as contact signals to determine whether the driver's hands and feet touch the steering wheel 600 and the accelerator pedal 700 . Specifically, when the hand touches the steering wheel 600, the driving mode switching module 130 detects a contact signal from the steering wheel pressure sensor 160, and when the foot touches the accelerator pedal 700, the driving mode switching module 130 detects a contact signal from the accelerator pressure sensor 170. When the hand leaves the steering wheel 600, the driving mode switching module 130 detects a non-contact signal from the steering wheel pressure sensor 160, and when the foot leaves the accelerator pedal 700, the driving mode switching module 130 detects a non-contact signal from the accelerator pressure sensor 170. The trigger judging module 135 can further identify whether it is a contact signal or a non-contact signal according to the duration of the pressure sensing signals sent by the steering wheel pressure sensor 160 and the accelerator pressure sensor 170 .

If only one leaves the use position, the manual driving mode is still maintained. When the initial vehicle 10 is running in the automatic driving mode, the vehicle driving mode switching system 100 can switch the automatic driving mode to the manual driving mode when it detects that the hands and feet are in contact with the steering wheel pressure sensor 160 and the accelerator pressure sensor 170 at the same time. If only one returns to the use position, the automatic driving mode is still maintained.

Specifically, when the vehicle 10 is initially driven in the manual driving mode, the hand will be held on the steering wheel 600 and the foot will be stepped on the accelerator pedal 700. When the vehicle driving mode switching system 100 detects that both are in the use position, the vehicle will The driving mode switching system 100 will maintain the manual driving mode; when the hands are off the steering wheel 600 while the feet are still on the accelerator pedal 700, the vehicle driving mode switching system 100 will detect that only the hands are off the steering wheel 600 while the feet are still in the use position , unless both of them leave the use position, the vehicle driving mode switching system 100 maintains the manual driving mode; when the foot is off the accelerator pedal 700 and the hands are still placed on the steering wheel 600, the vehicle driving mode switching system 100 will detect that only the foot is off the accelerator pedal 700, while the hands are still in the use position, unless both of them leave the use position, the vehicle driving mode switching system 100 maintains the manual driving mode; when the vehicle driving mode switching system 100 detects that both of them leave the use position, the vehicle driving The mode switching system 100 will switch to the automatic driving mode.

When the vehicle 10 is initially running in the automatic driving mode, the hands and feet will leave the steering wheel 600 and the accelerator pedal 700 at the same time. Driving mode; when the hands are off the steering wheel 600 and the feet are still on the accelerator pedal 700, the vehicle driving mode switching system 100 will detect that only the hands are off the steering wheel 600, while the feet are still in the use position, not both are in the use position , the vehicle driving mode switching system 100 maintains the automatic driving mode; when the foot is off the accelerator pedal 700 while the hands are still placed on the steering wheel 600, the vehicle driving mode switching system 100 will detect that only the foot is off the accelerator pedal 700 while the hands are still in use In the position, unless both are in use, the vehicle driving mode switching system 100 maintains the automatic driving mode; when the vehicle driving mode switching system 100 detects that both are in use, the vehicle driving mode switching system 100 will switch to manual driving mode.

If the current driving mode is switched to the manual driving mode, the prompting module 150 will send a manual mode switching prompt to the driver. The prompting method can be user interface prompting, sound prompting or seat vibration prompting. If the current driving mode is switched to the automatic driving mode, the prompting module 150 will send a prompt to the driver to switch the automatic mode. If the current driving mode is switched to the automatic driving mode, if the automatic driving module 200 detects that the navigation module 500 has no preset navigation, the prompting module 150 sends out a navigation setting prompt.
