Abstract

An automatic vehicle speed control system for controlling a braking means of a vehicle eg. brakes 16,17 having a control unit 22 having the aim of maintaining a target speed such as when descending a hill, has a push-button switch 32 operable by the driver to activate and de-activate the control unit. The system temporarily de-activates or puts on standby the target speed control if the vehicle speed is above 35 kph or an accelerator pedal 30 is depressed by more than 20{, and fully de-activates the target speed control if the vehicle speed is above 60 kph or if the vehicle ignition is switched off for more than 6 hours. If the control is temporarily de-activated, it resumes when the condition causing it is no longer detected. If the control is fully deactivated, it may be reactivated by the switch 32. Unit 22 also controls antilock braking and traction control.

Description

<Desc/Clms Page number 1>
Vehicle Speed Control The invention relates to control of a vehicle braking system, and in particular to the use of the braking system to control the descent of hills by the vehicle. It is particularly useful for off-road vehicles.
It is known from WO 96/11826 to provide a brake control system for a vehicle providing a speed control function in which the brakes are automatically controlled so as to limit the vehicle speed to a predetermined value such that, with the help of an anti-lock brake function, the descent of a steep hill can be controlled without the need for skilled inputs from the driver.
It can be a problem with such a system that if it is over-used the vehicle brakes and the control mechanisms for the system itself become prematurely worn. It is therefore known to de-activate the system under various conditions.
It is also known, for example from GB2297853 to provide a cruise control system which can be activated and de-activated by a user-operated switch, but which is also de-activated automatically under certain conditions, for example if the driver presses the brake pedal.
<Desc/Clms Page number 2>
The present invention provides a vehicle speed control system comprising braking means, control means arranged to provide a speed control function for controlling application of the braking means so as to maintain the vehicle at a target speed, and a driver operable switch for actuating the speed control function wherein the switch is arranged to be operated in the same way to activate and de-activate the function and the control means is arranged to de-activate the function without operation of the switch under predetermined de-activation conditions such that, after de- activation of the function, the function can only be re-activated by operation of the switch, and wherein under certain standby conditions the control means is arranged to put the function on standby, such that it is temporarily de-activated, and then to re-activate it without operation of the switch when predetermined re-activation conditions are met.
Preferably the standby conditions include the vehicle being powered down, for example by turning the vehicle ignition system off. Alternatively, or in addition, they may include the vehicle exceeding a predetermined standby speed.
The de-activation conditions may include the vehicle speed exceeding a predetermined de-activation speed. In this case the standby speed preferably lower than the de-activation speed.
<Desc/Clms Page number 3>
The re-activation conditions may include the vehicle speed falling below a predetermined speed, of the vehicle being powered up, for example by turning the vehicle ignition system on.
The de-activation conditions may include a predefined movement of an accelerator pedal of the vehicle, for example movement beyond a predetermined position.
The de-activation conditions may include the vehicle being powered down for a predetermined period of time, for example they may include an ignition system of the vehicle being turned off for said predetermined period of time.
An embodiment of the invention will now be described by way of example and with reference to the accompanying drawings, in which: Figure 1 is a schematic diagram of a vehicle incorporating a vehicle speed control system according to an embodiment of the invention, and Figure 2 is a graph showing operation of part of the system of Figure 1.
As shown in Fig. 1, the vehicle 10 includes an engine 2 and a manual transmission 4 for providing driving torque from the engine 2 via a differential 6 to two of the four vehicle wheels 12. Each wheel 12 is
<Desc/Clms Page number 4>
provided with a co-rotating brake disc 14 which is acted upon by a brake calliper 16. The brake callipers 16 are hydraulically operated and a hydraulic line 18 leads from each brake calliper to a hydraulic brake control system 20 which includes a hydraulic pump and valves so that it can increase and decrease the braking pressure independently of the position of the brake pedal 34. The hydraulic brake control system 20 is controlled by an electronic control unit 22.
Each wheel 12 also carries a co-rotating toothed wheel 24. An inductive sensor 26 is provided adjacent each toothed wheel 24 and provides a signal to the electronic control unit 22 in the form of a regular wave form voltage, the frequency of which is indicative of the wheel speed.
The accelerator pedal 30 has a continuously variable sensor in the form of a potentiometer associated with it which provides an analogue signal to the electronic control unit 22 which is dependent upon the position, or angle, of the accelerator pedal.
An ignition switch 36 is also provided which enables the driver to power up and power down the vehicle and to start the vehicle engine, and the control unit 22 receives a signal from the ignition switch 36 indicating whether the vehicle is powered up or powered down.
<Desc/Clms Page number 5>
A manually operable push-button switch 32 is also connected to the electronic control unit 22 for activation and de-activation of a speed control function as described below. If the speed control function is active, pressing the switch 32 will de-activate it, and if the speed control function is not activated, then pressing the switch will activate it.
In use, when the vehicle is being driven on-road, the speed control function will normally not be activated. Under these conditions the electronic control unit 22 operates the anti-lock braking function to prevent locking of the wheels if the driver brakes using the brake pedal 34. Also traction control is provided by the control unit 22. Both of these functions are carried out in known manner by monitoring the speed and acceleration of each wheel and a detected vehicle speed calculated from the speeds of all the wheels. The detected vehicle speed is calculated by using an average of all the wheel speeds, but ignoring the speeds of any wheels which are detected as locked or spinning. Locked wheels will be released by releasing braking pressure using the anti-lock valves in the hydraulic control unit 20, and spinning wheels will be slowed by applying a braking pressure from the pump.
If the driver wants to activate the speed control function he presses the switch 32. The electronic control unit then takes active control of the vehicle's speed, controlling the application and release of the brakes to limit
<Desc/Clms Page number 6>
the vehicle's speed to a target speed. This speed control is carried out regardless of the driver's operation of the brake pedal. However if the brake pedal is depressed far enough so that it produces a level of braking greater than that which would be provided by the speed control function, then the driver's demand for braking over-rides that of the speed control function and the vehicle is slowed below the target speed. However the speed control function is not de-activated and, if the speed again rises above the target speed, then the system applies the brakes again to limit the speed.
Referring to Figure 2, the target speed is set at a default value of, for example, 6 kph and can be varied by the driver by depressing the accelerator pedal, up to a maximum of 35 kph which corresponds to an angle of depression of the accelerator pedal of 20 . If either the accelerator pedal angle exceeds 20 , or the vehicle speed exceeds 35 kph, then the speed control function is put on standby, which means that it is de-activated temporarily because it is not designed to function under those conditions.
The function then remains in standby as long as either of these conditions continues. However, if at any time while the speed control function is in standby the accelerator pedal angle is below 200 and the vehicle speed is below 35 kph, then the speed control function is re-activated, and the brakes are again controlled whenever necessary so as to limit the vehicle speed to the target speed.
<Desc/Clms Page number 7>
If at any time the vehicle speed exceeds 60kph, then the speed control function is fully de-activated. When fully de-activated the speed control function will not be re-activated in response to a fall in the vehicle speed, but only by the driver operating the push button switch 32.
If the ignition switch is turned off and the vehicle powered down, the control unit 22 initially puts the speed control function into standby. This can be achieved, for example, by storing in EPROM the state of the function on powering down, i. e. whether it is activated or de-activated. Thereafter, if the ignition is turned on again, i. e. the vehicle is powered up, within a predetermined period of, for example, 6 hours, then the speed control function is re-activated, if it was activated on powering down, without operation of the push button switch 32. However, if the vehicle remains powered down for more than the 6 hour period, then the speed control function is fully de-activated. This means that, when the vehicle is again powered up, the speed control function will be inactive until the push-button switch 32 is operated by the driver. This means that, if the vehicle is stopped during a trip while the speed control function is active, and then restarted again, the speed control function will continue to be active.
However, if the vehicle is stopped for a longer period, for example over night, when it is more likely that it will be driven by a different driver, and less likely that the trip will be considered by the driver as a continuation of the previous one, the function will be de-activated.
