In-vehicle protection system using multiple processing units and/or using communication module to send positioning information
First Claim
1. An in-vehicle protection system, comprising:
- a signal input interface, arranged to receive at least an indication signal indicative of a status of a vehicle;
a vehicle protection circuit, comprising;
a first processing unit, arranged to perform predetermined action in response to abnormality of the vehicle;
a second processing unit, arranged to perform predetermined action in response to abnormality of the vehicle, wherein computing power of the first processing unit is different from computing power of the second processing unit; and
a controller, coupled to the signal input interface, the first processing unit, and the second processing unit, for receiving the indication signal, outputting the received indication signal to the first processing unit for further processing when the in-vehicle protection system operates under a first operational state, and outputting the received indication signal to the second processing unit for further processing when the in-vehicle protection system operates under a second operational state different from the first operational state; and
a global navigation satellite system (GNSS) module, arranged to obtain positioning information of the vehicle;
wherein after the second processing unit detects an abnormal status of the vehicle, the first processing unit sends at least one of the positioning information and vehicle alarm information indicative of the abnormal status through a communication network.

Abstract
An in-vehicle protection system includes a signal input interface, a vehicle protection circuit, and a global navigation satellite system (GNSS) module. The signal input interface receives an indication signal indicative of a status of a vehicle. The vehicle protection circuit includes a first processing unit, a second processing unit, and a controller. The first and second processing units perform predetermined action in response to abnormality of a vehicle, and have different computing power. The controller outputs the indication signal to one of the first and second processing units according to an operational state of the in-vehicle protection system. The GNSS module obtains positioning information of the vehicle. After the second processing unit detects an abnormal status of the vehicle, the first processing unit sends at least one of the positioning information and vehicle alarm information indicative of the abnormal status through a communication network.
