FAW Toyota New Reiz car has been officially off the assembly line, multiple car system was upgraded and improved. Here’s the automatic transmission, Adaptive Variable Suspension and parking assistance systems such as brief introduction, we want to help.
First, the automatic transmission
New Reiz car uses artificial intelligence shift control system, increase the driver’s intention support control (in conjunction with the motion pattern) to support the movement driving mode, this control increases the acceleration / deceleration reactivity.
When a selected gear S, the driver may be required by the shift lever and the shift gear selection paddles: when the shift lever ldquo; + rdquo; 1 s or pushed in a direction when a longer time, raised to the range gear S6; when the selector lever position D, the driver can shift toggle paddles temporarily to a driving gear in the desired field.
bis, the AVS (Adaptive Variable Suspension) system
the AVS system damping force control shock absorber is intended to enable the vehicle has a high stability, excellent driving and comfort.
1. The system elements
AVS system mainly includes a front (front left, right) acceleration sensors, the acceleration sensors, shock absorber control actuator and a control unit (FIG. 1).
FIG 1
2. The system control theory
(1) The system control theory
the AVS system control diagram shown in Figure 2.
FIG. 2
(2) the actuator element
① damping control actuator
of the magnetic pole rotor is directly connected with the control damper, the actuator uses a stepper motor, to achieve multi-stage control (FIG. 3).
FIG. 3
② damping valve
Figure 4
in order to vary the damping force, the system provides a ldquo; hard rdquo; and a damping valve ldquo; soft rdquo; damping valve (FIG. 4). Damper parts can be changed by rotating the rotary valve damping value, it changes the rotation of the rotary valve by ldquo; hard rdquo;, ldquo; soft rdquo; oil proportional damping valve (FIG. 5).
Figure 5
Depending on the operating conditions of the vehicle, the control system uses a variety of strategy (table 1). In the sport mode, the system uses the value of damping high damping force range.

Third, the brake control system
The brake control system control principle As shown in FIG. 6.
Figure 6
New Reiz increased joint steering control (FIG. 7) to improve the vehicle posture control.

Fourth, the electric power steering system
The electric power new Reiz employed The steering system includes a brake control system for coordinated control functions and control the voltage drop. In order to prevent EPS assist force due to the reduced power supply voltage drops due to the electrical part of the restricted operating voltage drop.
Fifth, the multi-communication (the MPX) system
Figure 8
New Reiz car multiplex communication equipment (the MPX) system uses three kinds of communication protocols, including CAN, LIN, and AVC-LAN, which is a network communication topology of FIG. 8 and FIG 9.

Sixth, power management control system
car uses the power management control system, the starter, the power mode and the CAN gateway functionality is integrated in the power management control unit.
Seven, parking aid
equipped with cutting-edge blog car parking aid system, the system is capable of flashing lights to form buzzer to notify the driver members from the sensor and the obstacle, the vehicle monitoring system using the side, the driver can monitor the area of the front passenger side of the vehicle.
1. The main element position sensor parking aid system
parking aid sensor system 10 shown in FIG.

When any of the ultrasonic sensor fails or stop working, multi-information display and buzzer.
2. Side monitoring system
side surfaces and the position of the main elements of the monitoring system monitoring area 12 is schematically shown in FIG.
