Abstract
When it is detected by velocity sensors (1-4, figure 1) that the vehicle is stationary 14 a slip threshold is set 15 by the controller (6, figure 1) to a low value so that virtually no wheel slip is allowed. Once the speed of the vehicle has reached a predetermined value, a higher wheel slip threshold is set 17 so that the vehicle's forward momentum can be maintained. This permits the vehicle to move off from rest without the wheels digging into a deformable surface, for example by controlling the throttle of the vehicle's engine (12, figure 1).
Description
Traction Control system for a vehicle This invention relates to
traction control systems for a vehicle and particularly to systems for controlling the vehicle's motion when setting off from rest on a deformable surface such as soft sand.
Known traction control systems compare a measurement of wheel slip with a threshold and reduce the torque applied to the driven wheels (usually by limiting engine output)if the slip threshold is exceeded. However, in addition to slowing down the rotational speed of the slipping wheel, the speed of vehicle is also reduced.
When driving on soft sand it is desirable to set a higher slip threshold than when driving on asphalt, for example, in order to maintain forward momentum and prevent the vehicle from bogging down.
EP 0574150 discloses a traction control system whereby the slip threshold is increased if it is detected that the traction control system is causing the vehicle to slow down too much.
WO 02/04242 describes a traction control system in which, on detecting entry onto a deformable surface, the wheel slip threshold is linearly increased over a period of time in order to increase the driven wheel speed and allow the wheels to churn through the loose surface.
While a high slip threshold is desirable while driving on sand, the opposite is true in the situation where the vehicle is starting of f from rest (on sand). If a high level of spin is allowed, then as the stationery vehicle attempts to pull away, the spinning wheels tend to dig into the sand and the vehicle is unable to move at all. Hence, a traction control system which permitted a vehicle to move off from rest on a deformable surface, such as sand, with the minimum of wheel spin and which enabled the vehicle to gain sufficient momentum in order to make good progress, would be advantageous.
According to a first aspect of the present invention, there is provided a traction control system for a vehicle for assisting the vehicle in starting off from rest on a deformable surface, the system including; means for measuring vehicle speed, and a controller connected to said means for measuring, wherein the controller is adapted to set a wheel slip threshold to a first value when the vehicle is stationary and to reset the wheel slip threshold to a second value, higher than the first value, when the vehicle speed reaches a predetermined value.
Preferably, the first slip threshold is set very low so that that virtually no slip is allowed (1 kph of overelip for example). This enables the vehicle to get moving and gradually build up some momentum. Once the vehicle has reached a speed of typically 5kph, the slip threshold is increased to a comparatively high value, thus permitting a high degree of slip and allowing the vehicle to maintain its momentum.
The traction control system may be further provided with means for measuring wheel slip and the controller may be further adapted to compare measured wheel slip with slip thresholds and to generate a control signal for a powertrain associated with the vehicle for adjusting a powertrain torque demand in order to reduce wheel slip to a target value.
Instead of or in addition to adjusting torque demand, the controller may be adapted to generate signals for controlling the braking of individual wheels in order to reduce slip.
The means for measuring vehicle speed and wheel slip may include wheel speed sensors.
The powertrain may comprise an internal combustion engine or an electric motor.
In one embodiment, the controller has a torque demand input and is adapted to continuously monitor powertrain torque demanded by the driver (for example, throttle pedal position) and to modify the powertrain torque demand on resetting the wheel slip threshold by an amount dependent on the magnitude of the driver-demanded powertrain torque. This permits the controller to reduce torque demand once the set speed is reached (for cases where the driver has pressed the throttle pedal close to its maximum extent), so that the engine speed and/or vehicle acceleration would not suddenly increase at an alarming rate due to the slip threshold changing to the higher value.
In accordance with a second aspect, the invention consists of a method of traction control for a vehicle for assisting the vehicle in starting off from rest on a deformable surface, the method including the steps of; monitoring vehicle speed, setting a wheel slip threshold to a first value when the vehicle is stationary, resetting the wheel slip threshold to a second value higher than the first value when the vehicle speeds reaches a predetermined value.
An embodiment of the invention will now be described, by way of example only, with reference to the drawings of which; Figure 1 is a schematic block diagram of a traction control system in accordance with embodiment of the invention, and Figure 2 is a flowchart illustrating operation of the traction control system of Figure 1.
In the example of Figure 1, the traction control system is suitable for incorporation in a vehicle having four driven wheels. The outputs from four wheel sensors 1,2,3,4, each being associated with a respective one of four driven wheels (not shown) are connected to a speed calculator 5. The speed calculator 5 has two outputs which are connected to a controller 6. A first output on line 7 provides the controller 6 with a measurement of vehicle speed. A second output on line 8 provides the controller 6 with a measurement of wheel slip. A further input to the controller 6 on line 9 provides a terrain type (eg.sand) signal. This input is supplied by a driver-operated switch 10. A driver demand signal is supplied from a throttle pedal position sensor 11 to the controller 6. An output of the controller 6 supplies an engine torque demand signal to an internal combustion engine 12. This signal may typically be used to control a throttle of the engine 12, for example.
In this example, the speed calculator 5 can be arranged to provide a measurement of vehicle speed for the controller 6 by calculating vehicle speed as the speed of the slowest wheel or as an average of the speed of two or more wheels.
The speed calculator 5 can therefore also detect when the vehicle is stationary. Further, the speed calculator 5 provides a measurement of wheel slip to the controller 6 by comparing individual wheel speeds (as provided by the wheel speed sensors 1-4) with the calculated vehicle speed.
The controller 6 has stored therein, two values of wheel ship threshold for comparison with a measured value of wheel slip under certain operating conditions to be described below.
The controller 6 continuously monitors wheel speed and wheel slip and reduces engine torque demand when a wheel slip threshold is exceeded. Hence, the degree of wheel slip can be kept below a predetermined level.
With reference to the flow diagram of figure 2, operation of the traction control system of figure 1 will now be described.
At step 13, the controller 6 interrogates the driver-operated terrain type selector switch 10 to determine if the vehicle is on sand. This switched 10 can be a rotary type switch whereby the driver sets it to the type of terrain the vehicle is traversing, for example asphalt, mud, sand.
If it is determined that the vehicle is on sand, then the process proceeds to step 14 whereby the controller 6 interrogates the speed calculator 5 to ascertain whether the vehicle is stationary or not.
If the vehicle is stationary then the controller 6 selects a lower one (Ti) of the two stored slip thresholds for comparison with the wheel slip measurements (step 15).
The controller 6 continues to monitor vehicle speed (step 16). When vehicle speed reaches a predetermined value (5kph in this example), a higher (T2) of the stored slip thresholds is selected by the controller 6 for comparison with the wheel slip measurements (step 17).
