ANTILOCK BRAKE SYSTEM 4F-7
ABD SYSTEM DESCRIPTION
General: The Automatic Brake Differential Lock (ABD) is a traction system by means of brake intervention only, available in a low speed range (< 60kph). It workes on µ-split roads with sidewise different friction coefficients.
The spinning driven wheel is braked and the drive torque can be transferred to the wheel on the high- µ side.
During ABD active, the ABD information lamp is blinking.The temperature of the brakes is calculated by a mathematical model and ABD is switched passive if the calculated temperature is greater than a threshold value(500 °C).
ABD is permitted again, when the calculated temperature is less than 350 °C.
Control Algorithm: The input signals for the control algorithm are the filteredwheel speed signals from the ABS speed processing. With the speed difference of the driven wheels, the control deviation is calculated. If the control deviation exceeds a certain threshold value,
the wheel with the greater slip is braked actively. The threshold value depends on the vehicle speed:It is reduced with increasing vehicle speed down to a constant value.
Pressure Modulation: Depending on the control deviation and the wheel acceleration of the spinning wheel, pressure increase, hold and decrease are made.
The pressure modulation is done with the conventional control with the valves. ASV, USV, EV and AV according the the following table:
Speed Range: ABD is available in the speed range 60 kph.
Above 60 kph vehicle speed, ABD is passive. It is possible to initiate ABD operation up to a vehicle speed of 55kph.

5A-18 AUTOMATIC TRANSMISSIONINTRODUCTION
The BTR Automotive Model 74 Four Speed Automatic Transmission is an electronically controlled overdrive four
speed unit with a lock-up torque converter. The lock-up torque converter results in lower engine speeds at cruise and
eliminates unnecessary slippage. These features benefit the customer through improved fuel economy and noise
reduction. Refer to table 1.1 for details of power, torque and configuration.
Of primary significance is the transmission control unit (TCU) which is a microprocessor based control system. The
TCU utilizes throttle position, rate of throttle opening, engine speed, transmission output speed, transmission sump
temperature, gear selector position and mode selector inputs, and in some applications a ‘kickdown’ switch to control
all shift feel and shift schedule aspects.
The TCU drives a single proportional solenoid multiplexed to three regulator valves to control all shift feel aspects.
The output pressure of this solenoid is controlled as a function of transmission sump temperature to maintain consistent
shift feel throughout the operating range.
Shift scheduling is highly flexible, and several independent schedules are programmed depending on the vehicle.
Typically the ‘NORMAL’ schedule is used to maximise fuel economy and driveability, and a ‘POWER’ schedule is used
to maximise performance. ‘WINTER’ schedule is used to facilitate starting at second gear.
Figure 1.1 details the differences between conventional and electronic transmission control systems.
