Definitions
- Cruise control is now usual in motor vehicles, e.g. cars, trucks and buses.
- An object of cruise control is to achieve a uniform predetermined speed. This is done either by adjusting the engine torque to avoid retardation, or by applying braking action on downhill runs where the vehicle is accelerated by its own weight.
- a more general object of cruise control is to provide convenient driving and better comfort for the vehicle's driver.
- a driver of a vehicle equipped with cruise control usually chooses a set speed v set as the speed he/she wishes the vehicle to maintain on level roads.
- a cruise control then supplies an engine system of the vehicle with a reference speed v ref used for control of the engine.
- the set speed v set may thus be regarded as an input signal to the cruise control, whereas the reference speed v re f may be regarded as an output signal from the cruise control and is used for control of the engine.
- CC cruise control
- v ref constant reference speed
- v set a desired speed chosen for example by him/her
- v set a desired speed chosen for example by him/her
- v set a desired speed chosen for example by him/her
- the value of the reference speed v re f changes only when adjusted by the driver while the vehicle is in motion.
- the reference speed v re f is then sent to a control system which controls the vehicle so that its speed corresponds when possible to the reference speed v re f.
- Knowledge of the road section ahead may for example comprise information about prevailing topology, road curvature, traffic situation, roadworks, traffic density and state of road. It may further comprise a speed limit on the section ahead, and a traffic sign beside the road.
- location information e.g. GPS (global positioning system) information, map information and/or topographical map information, weather reports, information communicated between vehicles and information provided by radio. All this knowledge may be used in a variety of ways. For example, information about a speed limit on the road ahead may be used to achieve fuel efficiency by lowering the vehicle's speed before reaching a lower speed limit. Similarly, knowledge of a road sign which indicates for example a roundabout or intersection ahead may also be used to achieve fuel efficiency by braking before the vehicle reaches the roundabout or intersection.
- At least one of these rules is that the reference value on which the vehicle speed is to be regulated is a value corresponding to the set speed v set if said first prediction v pre d jnew ret of the vehicle speed is below the lower limit value v m j n and at the same time said second prediction v pre d Tnew acc of the vehicle speed is above the upper limit value v ma x.
- the at least one reference value is a value which represents said first predicted vehicle speed Pred_Tnew_ret if a minimum value for said first predicted speed is equal to or above the lower limit value v m j n and if also a maximum value for said first predicted speed is equal to or above a further upper limit value v max2 which is related to a set speed v set .
- Figure 5 illustrates the vehicle's predicted speeds according to an embodiment of the invention.
- a number of simulation cycles may be done along the length of the horizon.
- a simulation cycle Sj may comprise a number N of simulation steps which may be conducted at a predetermined rate f. According to the invention, the following steps are performed during such a simulation cycle Sj;
- n is the vehicle's engine speed and i, ol the vehicle's total transmission ratio.
- the vehicle's acceleration Acc is given by
- dP K v, ml (eq.8) where AT is a time constant, e.g.0.9s, and v init is prevailing vehicle speed at the beginning of the simulation.
- the reference speed v ref is determined to a value which represents said first predicted vehicle speed v pre d Tn ew_ret if a minimum value for said first predicted speed is equal to or above the lower limit value v m in and if also a maximum value for said first predicted speed is equal to or above a further upper limit value v ma x 2 which is related to a set speed v set .
- the further upper limit value v max2 corresponds to the set speed plus a constant ci, i.e.
- the cost functions J-mew_ret , JTnew_acc, JTk+new_ret and JTk+new_acc for said first prediction v pre d_Tnew_ret, said second prediction pred_Tnew_acc, said further first prediction v pre d _Tk+new_ret and said further second prediction v P red_Tk+new_acc of the vehicle speed Vpred Tnew_ret, of the vehicle speed are subjected to a cost function comparison followed by determining said at least one reference value on the basis of said comparison to arrive at lowest cost.
- the reference value is set to whichever from among said first prediction, said second prediction, said further first prediction and said further second prediction of the vehicle speed results in least cost. This is done in this embodiment at step S23 for acceleration and at step S33 for retardation ( Figure 4).
