Abstract

A system for detecting a motion of an occupant seated in a vehicle. The system includes a sensing electrode located proximate to the occupant and configured to transmit a signal representative of a current in the sensing electrode. The system also includes a receiver including a controller and coupled to an antenna. The receiver is configured to detect a change in the transmitted signal based on a presence of the occupant and a set detection condition, and generate detection information based on the set detection condition. The controller is configured to change a state of a vehicle component based on the generated detection information.

First claim

What is claimed is:

1. A system for controlling a component of a control module of a vehicle operated by a driver and configured for operation in semi-autonomous and autonomous driving modes, comprising:
a first electrode located proximate to the driver of the vehicle and configured to transmit a control signal representative of a current in the first electrode through the driver of the vehicle via a body area network;
a second electrode proximate to a passenger of the vehicle and configured to transmit a second control signal representative of a current in the second electrode through the passenger of the vehicle via a passenger body area network; and
a receiver coupled to an antenna located proximate to the component, the receiver being configured to detect the transmitted control signals and determine the presence of the driver and passenger proximate to the component based on detection information indicating a proximity between an appendage of the driver and the antenna; wherein the determination of the presence of the driver and passenger is provided to a controller and
wherein the controller is configured to determine whether the driver may control the component based on a driving mode of the vehicle;
wherein the controller is configured to prohibit, based on the determination of whether the driver may control the component, the driver from controlling the component by disabling touched based control of the component when the vehicle is in a manual driving mode, and
wherein the controller is configured to permit the driver to control the component when the vehicle is in one of the semi-autonomous driving mode and the autonomous driving mode; and
wherein the controller is configured to permit the driver to control the component when the vehicle is in one of the semi-autonomous driving mode and the autonomous driving mode; and
wherein the controller is configured to permit the passenger of the vehicle to control a second controller that independently controls an operation of the vehicle when the vehicle is in semi-autonomous and autonomous driving modes.

2. The system of claim 1 , wherein the first and second electrodes are located in a seat of the vehicle.

3. The system of claim 1 , wherein the first electrode is located in a steering wheel of the vehicle.

4. The system of claim 1 , wherein the controller is configured to generate a prompt indicating the touched based control of the component is disabled.

5. The system of claim 1 , wherein the first electrode transmits the control signal through the driver over one of a discrete frequency and a time phase frequency.

6. The system of claim 1 , wherein the receiver is located in a center console of the vehicle.

7. The system of claim 1 , wherein the receiver is located in a terminal device in the vehicle and the controller prohibits, based on the determination, the driver from controlling the terminal device by disabling touched based control of the terminal device when the vehicle is in a manual driving mode and the driver is in contact with a steering wheel, and generates a prompt indicating the touched based control of the terminal device is disabled.

8. The system of claim 7 , wherein the terminal device is one of a mobile phone, a tablet, a wearable electromechanical device and a laptop.

9. The system of claim 1 , wherein the receiver is located in a terminal device in the vehicle.

10. The system of claim 9 , wherein the terminal device is one of a mobile phone, a tablet, a laptop, a camera, a wearable electromechanical device, a camcorder, a radar detector and an independent navigation unit.

11. The system of claim 1 , wherein the receiver is located in an instrument panel of a vehicle.

12. A system for controlling a vehicle operated by a driver and configured for operation in semi-autonomous and autonomous driving modes, comprising:
a first electrode located proximate to the driver and configured to transmit a control signal representative of a current in the first electrode through the driver of the vehicle via a body area network;
a second electrode proximate to a passenger of the vehicle and configured to transmit a second control signal representative of a current in the second electrode through the passenger of the vehicle via a passenger body area network; wherein the system is configured to detect the presence of the passenger based on the transmitted second control signal; and
a receiver coupled to an antenna located in a steering wheel of the vehicle, the receiver configured to detect the transmitted control signal based on contact between the driver and the steering wheel, wherein the receiver includes a first controller configured to determine whether the driver is in contact with the steering wheel;
wherein a second controller is configured to control the operation of the vehicle when the vehicle is in one of the semi-autonomous driving mode and the autonomous driving mode and the driver is not in contact with the steering wheel; and
wherein the second controller is configured to permit the passenger to control the second controller when the vehicle is in one of the semi-autonomous driving mode and the autonomous driving mode.

13. The system of claim 12 , wherein the first electrode transmits the control signal through the driver over one of a discrete frequency and a time phase frequency.

14. The system of claim 12 , wherein the second controller is configured to allow the passenger to slow down and stop the vehicle in an emergency situation.
