The principle of the car audio system is same as that of the home audio system.
However, the car audio system is used in a vehicle where the conditions are severe. The following characteristics are observed.

Diagnose Automotive Radio Reception Problems
1.Outline
Since the car radio depends on the antenna length and vehicle noise, the broadcast service area in which the vehicle can receive programs clearly becomes small.
The noise is called impulse Read more Diagnose Automotive Radio Reception Problems
Automotive Audio System outline
A car audio is a device that creates a comfortable driving environment, like at the air conditioner.
The talk of a disc jockey or music from the car audio puts the driver at ease.

Cruise Control System Adaptive Laser Cruise Control Function
1.General
This system maintains the vehicle at the speed the driver has set, as long as there are no vehicles in front in the same lane. If the system detects a vehicle being driven in front at a slower Read more Cruise Control System Adaptive Laser Cruise Control Function
Cruise Control System Input Signal Check Function
1.General
Whether signals from the speed sensor and those from the order switches are sent to the cruise control ECU normally can be conformed to the following by reading the blinking pattern of the Read more Cruise Control System Input Signal Check Function
Cruise Control System Warning Indication
1.General
Notifies the driver if trouble occurs with the CCS.
2.Warning indication
If the cruise control ECU does not receive a vehicle speed signal for a predetermined period of time, or if cruise Read more Cruise Control System Warning Indication
Cruise Control Actuator Operation
1.Motor and limit switch
The motor revolves either clockwise or counterclockwise in response to acceleration or deceleration signals from the cruise control ECU, thereby altering the opening angle of Read more Cruise Control Actuator Operation
Cruise Control System ETCS-i controlled type 2 of 2
7.Higher speed limit control function
The higher speed limit is the highest speed at which the cruise control can be set. It is approx. 200 km/h [124 mph]. The cruise control cannot be set above this Read more Cruise Control System ETCS-i controlled type 2 of 2
Cruise Control System ETCS-i controlled type 1 of 2
Engine ECU
The engine ECU basically controls the engine, but in the vehicle with the ETCS-i, since the throttle valve-opening angle can be controlled electrically, this type of vehicle can also have Read more Cruise Control System ETCS-i controlled type 1 of 2
Construction of Cruise Control System
1.Cruise control ECU
The ECU receives signals from the vehicle speed sensor and various switches, and processes them according to a pre-stored program.
Based on these signals, the ECU sends control Read more Construction of Cruise Control System
