SOUL is Dongfeng Yueda Kia produced a new car, a compact car to a home station wagon and a small SUV hybrid models of the identity as a selling point, rather peculiar appearance, spacious interior. Vehicle equipped Gamma; Type 1.6 L, beta; 2.0 L engine type, matching 5-speed manual transmission and a 4-speed automatic transmission, equipped with an electronic stability control (ESC) system, a variable displacement air conditioning compressor and an electric power steering system. In order to facilitate the readers understanding of the car, we briefly introduce some highlights of this technology to it.
First, the vehicle electrical system
1.CAN network communication system (FIG. 1)
FIG 1
SOUL dashboard is not connected to the high-speed drivetrain CAN communication system, in order to display the current vehicle speed, a vehicle speed signal from a receive only TCM (or PCM) a. Because there is no smart key system SOUL configuration, there is no configuration of the vehicle body (low) CAN communication system. The instrument panel by separate wires to several output speed signal the control unit. ESC (Electronic stability control) system, a steering wheel angle speed sensor connected to the control unit through a CAN communication line independent ESC systems. Further, the output signal of the yaw rate sensor is also transmitted to the control unit by the ESC system independent CAN communication line.
Function 2. The vehicle body control unit
FIG. 2
SOUL body control module (FIG. 2) is Sportage of BCM The R & D, about 30 percentage changes. In the absence of anti-theft alarm system, starting system burglar alarm horn relay and relay it does not exist, but the configuration of the remote control system can be configured depending on the region ldquo; emergency horn sound rdquo;, ldquo; Horn responded rdquo; function. Further, the car is not applied CAN communication interface.
SOUL body main function of the control unit includes a front water jets / wiper control, an intermittent wiper control (non-vehicle speed sensor), the wiper blade fog control, rear wiper / sprinkler control (including intermittent control), Delay control interior lights, power window control timer (not equipped with safety power window), a door open warning (warning the key is removed), lighting control ignition key hole, the SRS collision automatic door unlock signal, the ignition key tips, central locking and unlocking the door lock control, automatically cut off the tail lights, rear defroster timing control, by remote control interior lights automatically via diagnostic diagnosis (not support user options feature, the DTC does not support), password (up to four input remote control), when the working key sound control latch (latch signal input remote horn ring 1) and the seat belt warning lamp and a buzzer control.

The control principle of the tailgate (FIG. 7) shows.
Second, the air conditioning system
SOUL vehicle air conditioning systems use a variable swash plate type compressor, the refrigerant quantity circulating in the cooling load can be controlled continuously according to the desired chamber. The compressor of this type has the following advantagespoint.
(1) controlling the compressor does not require frequent ON / OFF, you can maintain a constant cooling effect.
(2) low noise, and vibration.
due to the low ON / OFF cycle, noise and vibration reduction. Because the refrigerant pressure can be controlled at an optimum level, thus reducing the overall cooling load required.
(3) fuel efficiency
The refrigeration cycle as a result of the refrigerator control variable load, the engine load is reduced, thereby improving fuel efficiency.
