When transmitting an instruction for activating an immobilizer function to a subject vehicle, a base station also transmits a given ID code for releasing the immobilizer function. An immobilizer ECU that receives the instruction and the given ID code, prohibits an engine from being started by other than a key having the given ID code. Therefore, a regular user alone, who owns a key having the given ID code, can start the engine.

Each of ECUs constituting a system of a vehicle is registered with authentication IDs of other ECUs. The each of ECUs determines whether the other ECUs are regular by comparing the registered IDs with authentication IDs newly obtained from the other ECUs when the system is started. When a certain ECU within the other ECUs is determined to be not regular, the certain ECU is prohibited from being used in this system. Further, when a new ECU is substituted or added, a terminal confirms whether the new ECU is unused in another vehicle and is thereby enabled to be usable by transmitting an authentication ID of the new ECU to a management center. When the new ECU is confirmed to be enabled to be usable, authentication IDs registered in the respective ECUs are updated.

A method of controlling a vehicle engine involves determining a predetermined start operation, which is usually performed by a driver when the driver starts a parked vehicle, and that is not exclusively performed for starting the vehicle engine, verifying a code with a portable device after determining the predetermined start operation, and starting an engine automatically after successfully verifying the code. An engine control device has a start determining mechanism for determining a predetermined start operation, which is usually performed by a driver when the driver starts a parked vehicle, and that is not exclusively performed for starting a vehicle engine, a verifying mechanism for verifying a code with a portable device after determining the predetermined start operation, and a starting mechanism for controlling an automatic engine start after successfully verifying the code.

An automotive burglar alarm unit has an intrusion or equivalent security sensor. The burglar alarm unit can operate in an alarm set state for generating alarm, with a security sensor OFF mode for invalidating a signal of the security sensor. A user can use a portable phone to transmit a sensor ON signal via an information center. When the burglar alarm unit receives the sensor ON signal, the burglar alarm unit shifts into an alarm set state of security sensor ON mode so that the burglar alarm unit can generate alarm in response to a signal of the security sensor. Furthermore, the user can transmit a sensor OFF signal. In response to the sensor OFF signal, the burglar alarm unit shifts into an alarm set state of security sensor OFF mode so that no alarm is generated based on the signal of the security sensor.
摘要:
A vehicle intrusion monitoring system that eliminates unnecessary image capture and transmission by controlling the timing of image capture by a camera installed inside a vehicle. A control ECU in the vehicle intrusion monitoring system issues a first image capture command to a camera triggered by an abnormality detected by a sensor while the system is in watch state. Then, the control ECU issues a second and further image capture commands only when an intrusion detector picks up an intruder inside the vehicle to eliminate unnecessary image capture and transmission.

An anti-theft device monitors an object or person approaching a vehicle from the surrounding area of the vehicle by using a surrounding area sensing sensor when an authorized vehicle user moves away from the vehicle which causes the anti-theft device to be activated. If the anti-theft device detects the object or person, the anti-theft device activates an alarm. The anti-theft device transmits images and surrounding area details of the vehicle to the information center. If the vehicle is illegally accessed, the occurrence of any illegal activity is detected by a break-in sensor that issues a break-in alarm, simultaneously with the transmission of vehicle information to the information center, indicating the current disposition of the vehicle. Then, the information center determines that the vehicle is being illegally operated and transmits the vehicle information accumulated at that moment to a manager terminal.

A vehicle security device for improving the security level of a vehicle. The vehicle security device is connected to an engine and communicates with a portable device. A smart ECU performs a first coded communication to establish mutual authentication with the portable device. An ID code box is connected to the smart ECU, has a first code and a second code, and does not communicate with the portable device. The ID code box performs a second coded communication using the first code to establish a second mutual authentication with the smart ECU. An engine ECU performs a third coded communication using the second code to establish a third mutual authentication with the ID code box. The engine ECU enables the engine to be started when every one of the first, second, and third mutual authentications are established.

A smart key carried with a user is provided with switches for monitoring a vehicle in remote places, such as a departure-time monitor switch, a return-time monitor switch and an all item monitor switch. The switches are associated with monitor information indicating various vehicle states. When the departure-time monitor switch is operated, the cellular phone receives monitor information such as parking position, rainfall state, etc. useful to the user at departure time from the vehicle. Similarly, when the return-time monitor switch is operated, the cellular phone receives monitor information useful at return time such as door open/closed state and lock state. When the all item monitor switch is operated, the cellular phone receives monitor information of all monitor items.
