Cruise Control for 1GR–FE

The cruise control system is a constant vehicle speed controller in which control of the switch on the instrument panel makes

it possible to automatically adjust the opening of the engine throttle valve without depressing of the accel pedal

1 Set Operation

When the main SW is turned on, the system starts preparations necessary for the cruise control and turns on the indicatorlight in the combination meter

2 Set Speed Control

When the – SET SW is operated with the cruise control main SW turned on during travelling, the constant vehicle speed iscontrolled

3 Coast Control

When the – SET SW is kept turned on during cruise control travelling, the engine control module controls the throttle valve todecelerate the vehicle Every time the – SET SW is turned on instantaneously, the vehicle speed is deceleratedapproximately 1.6 km/h

4 Accel Control

When the + RES SW is kept turned on during cruise control travelling, the engine control module controls the throttle valve toaccelerate the vehicle Every time the + RES SW is turned on instantaneously, the vehicle speed is acceleratedapproximately 1.6 km/h

5 Resume Control

When the vehicle speed is within the low speed limit (Approximately 40 km/h, 25 mph) if the cruise control is cancelled, use

of the + RES SW accelerates the vehicle to the speed level used before canceling the cruise control

6 Manual Cancel Mechanism

If any of the following signals is input during cruise control travelling, the cruise control is cancelled

∗ The stop lamp SW is turned on

∗ The CANCEL SW is turned on

∗ The main SW is turned off

∗ Gear is shifted from D position to other positions than D (A/T)

∗ Clutch pedal depresed (M/T)

7 Auto Cancel Function

If any of the following conditions is encountered, the cruise control is automatically cancelled

∗ The stop lamp SW wiring is faulty or short–circuited

∗ The vehicle speed signal is faulty

∗ The electronically controlled throttle malfunctions

∗ The actual vehicle speed becomes –16 km/h slower than the set speed

∗ The actual vehicle speed becomes slower than the minimum speed limit

8 Overdrive Control Function

Overdrive is sometimes cut off on gradients during cruise control driving When end of climbing gradient is determined bythrottle opening degree information after overdrive is canceled, control is reset to overdrive condition after overdrive resettingtimer operation Also, when overdrive is cut off during accelerator resuming control, control is reset to overdrive conditionwhen accelerator resuming control is finished

∗ When the front wheels lose grip in relation to the rear wheels (Strong front wheel skid tendency)

∗ When the rear wheels lose grip in relation to the front wheels (Strong rear wheel skid tendency)

2 Electronic Brake–Force Distribution

Skid control ECU with actuator distributes appropriate brake–force to front and rear wheels (Control of brake–forcedistribution to front and rear wheels) corresponding to the vehicle driving conditions It also makes effective use of rear wheelbrake–force to match loading condition and decelerating of the vehicle, resulting to reduce depressing of brake pedal and toensure effective braking In braking during making a turn, the ECU controls appropriate brake–force distribution to right andleft wheels (Control of brake–force distribution to right and left wheels) to ensure stability and braking of the vehicle

3 Downhill Assist Control Operation

The downhill assist control operation controls braking action of each wheel to help prevent out–of–balance vehicle posturewhen descending a steep hill or traveling at a speed exceeding the threshold of wheel gripping capability When the downhillassist control is in operation, the brake system controls vehicle speed within the range of 5 to 7 km/h

For the downhill assist control to be operative all of the following conditions have to be met:

∗ Downhill assist control switch = ON

∗ Transfer L4 selected

∗ Vehicle speed is 5 km/h or more, but less than 25 km/h

∗ Accelerator pedal OFF

∗ Brake pedal OFF

4 Hill–Start Support Control Operation

When starting on a steep hill for ascending, the hill–start support control automatically puts the brake on momentarily – fromthe moment when the driver releases his foot from the brake pedal until he steps on the accelerator pedal – to help the driverstart the vehicle safely and smoothly

Please bear in mind, however, that it activates the brake system for only 3 seconds

For the hill–start support control to be operative all of the following conditions have to be met:

6 Auto LSD (2WD)

Auto LSD fulfills the function of LSD (Limited Slip Differential) by using the system of TRAC It controls to focus on ’gettingout’, which ensures to recover from run–off condition and to take off on roads with much travel resistance such as sand

This system controls the respective brake fluid pressures acting on the disc brake cylinders of the right front wheel, left frontwheel and rear wheels when the brakes are applied in a panic stop so that the wheels do not lock This results in improveddirectional stability and steerability during panic braking.

1 Input Signals

(1) Speed sensor signal

The speed of the wheels is detected and input to TERMINALS (B) 10, (B) 15, (B) 40 and (B) 44 of the skid control ECUwith actuator

(2) Stop lamp SW signal

A signal is input to TERMINAL (B) 14 of the skid control ECU with actuator when the brake pedal is depressed

2 System Operation

During sudden braking the skid control ECU with actuator has signals input from each sensor, which controls the current tothe solenoid inside the actuator and lets the hydraulic pressure acting on each wheel cylinder escape to the reservoir Thepump inside the actuator is also operating at this time and it returns the brake fluid from the reservoir to the master cylinder,thus preventing locking of the vehicle wheels

If the skid control ECU with actuator judges that the hydraulic pressure acting on the wheel cylinder is insufficient, the current

on the solenoid is controlled and the hydraulic pressure is increased Holding of the hydraulic pressure is also controlled bythe skid control ECU with actuator, by the same method as above Pressure reduction, holding and increase are repeated tomaintain vehicle stability and to improve steerability during sudden braking
