Definitions
- the invention relates to a method for limiting the pulling / pushing force in a
- a caravan or caravan is a trailer for a motor vehicle, in which a suitable device for the living and staying of people is installed.
- Such a caravan is traditionally pulled by the towing vehicle in road traffic as a trailer without any own drive.
- it is a single-axle trailer or a trailer with one
- motor vehicles Regardless of the type of drive, motor vehicles have an ever lower trailer load or tractive force compared to the past. Trailer operation or very heavy wear on the engine, clutch, transmission, brakes and tires and can lead to radiator and brake overheating. This results in a greatly increased energy consumption or fuel consumption and a deterioration in the
- a motor vehicle as a towing vehicle must therefore be selected with a correspondingly high vehicle weight, powerful engines and possibly all-wheel drive, which leads to additional costs and increased fuel or energy consumption in normal operation.
- hybrid vehicles and purely electric vehicles are increasingly being used as motor vehicles. If such vehicles pull a trailer, there is a noticeable or enormous reduction in the range of a purely electric vehicle and this can result in hybrid vehicles that the required additional power of the electric drive is not available for a sufficiently long time because the battery is exhausted. The range is still significantly limited by the current battery technology.
- the maximum drive power of the electric vehicles is usually designed for priority use in inner-city operation.
- the permissible trailer load of a towing vehicle is essentially determined by four factors. First of all by the maximum tractive effort of the towing vehicle, which is a function of the engine power and the wheel drive power that can be transmitted to the ground by the vehicle weight.
- the second determining factor is the maximum braking power of the towing vehicle as a function of the brake design and also that of the wheel load or the
- the third determining factor of the trailer load is the maximum lateral force, which can lead to "buckling" of the trailer, especially when braking in a curve.
- the shear force is a function of the transferable total traction to the
- the wheel load-dependent traction force of a wheel is vectorially composed of the acting transverse force and the currently acting acceleration force, be it as a braking or driving force.
- the fourth factor is the structural strength of the towbar.
- the load on the trailer coupling results from the static and
- the present invention is based on the object of providing a trailer, in particular a caravan, which can also be used with towing vehicles
- Towing vehicle can be moved in road traffic ..
- Driving or braking the electric motors complies with the tractive / pushing forces for a lower trailer load than the permissible total weight of the trailer. A minimum and / or maximum limit value of the force, in particular in the longitudinal direction of the vehicle, is observed.
- the range of electric vehicles in trailer operation can be significantly increased, particularly due to the high energy stored in the trailer.
- a lower trailer load is advantageously simulated by the control system by additional acceleration of the trailer wheels or braking. This means that even very light vehicles with low drive power and weakly designed chassis can pull large and heavy trailers. For example, it is conceivable that even vintage cars with only a small trailer load can pull a caravan.
- the stress and wear on the pulling motor vehicle is significantly reduced by providing support during peak loads, when starting off and when driving uphill.
- a towing vehicle
- the forces in the longitudinal direction can be recorded.
- Energy supply in the trailer in particular the recuperation brake, can be permanently controlled in addition to the strain relief in the drive case, and thus the thrust relief can be ensured.
- the recuperation brake In addition to regenerative braking, the
- Service brake can be activated electrically to assist.
- control increases the vertical load and thus the possible lateral force of the rear wheels of the towing vehicle by braking the electric motors.
- the trailer can be braked “automatically” when cornering, in order to increase the traction of the rear axle of the towing vehicle through increased vertical load.
- control can control the electric motors of the two sides of the trailer separately and thereby exert a steering torque on the trailer.
- the control can also control a service brake of the wheels, optionally the service brake on each side of the trailer individually.
- the sensor means advantageously comprise force sensors and / or force displacement sensors.
- Capture trailers especially via sensors or a camera and
- one comprises
- Control software of the control an observer, which comprises a system model of the trailer, in particular based on the rotational speeds of the wheels,
- Lateral acceleration and articulation angle between the towing vehicle and trailer compares the actual values, in particular yaw rates, and controls the electric motors and / or controls the service brake.
- the regulation of the tension / shear relief can be done by different sensors together or individually and / or model-based.
- a model-based electronic system observer on the trailer can, similar to an ESP, determine the driving dynamics target values of the float and yaw angle of the trailer in relation to the towing vehicle and with real values of e.g. Compare yaw rate sensor and intervene to correct driving dynamics via the electric motors and service brake.
- control can exert a pushing force on the towing vehicle via the driven wheels, particularly when starting off.
- the trailer axle when starting off, for example, in addition to the driven axle of the towing vehicle, the trailer axle also acts as a drive axle for the towing vehicle and a better overall traction is achieved, similar to a four-wheel drive vehicle. Basically, it is also possible to use a
- the towing vehicle free of lateral force and thus to map a reserve function, especially for electric vehicles, in which the trailer serves as the sole emergency drive, so to speak.
- the thrust is based on the control technology Adjust traction potential of the towing vehicle, or limit it to a generally uncritical value.
- This "emergency function" can serve, for example,
- a slight recuperation in the pushed "towing vehicle” can maintain a minimal state of charge in the vehicle and thus supply driving safety systems such as brakes, steering and lights.
- a retarder function can be integrated with a full battery, which can supplement or replace the service brake.
- the control objective is a force effect which is directed onto the longitudinal axis of the vehicle essentially without lateral force.
- Actuators are the wheel-specific electric motors (torque vectoring), possibly supplemented by the service brake.
- Suitable sensors are on the one hand force sensors at the coupling point in all three spatial directions (on a trailer or towing vehicle) and on the other hand force or force-displacement sensors (spring deflection) in
