    15 20 25 30 A disadvantage of said filter functions is that they are associated with certain time delays. In this case, a driver may experience that the vehicle's engine does not respond in the desired manner to the throttle request. This can be perceived as unpleasant or annoying for a driver.
    Furthermore, jerks in a driveline can occur when operating a vehicle with said filter functions, in particular when requesting a powerful throttle, such as when starting the vehicle from a standstill. These jerks in the driveline can in themselves cause discomfort to the driver. In the event of these jerks, the vehicle may further oscillate or rock, which may further reinforce the driver's feeling of discomfort.

    SUMMARY OF THE INVENTION An object of the present invention is to provide a new and advantageous method for limiting torque build-up of an engine of a motor vehicle.
    Another object of the invention is to provide a new and advantageous device and a new and advantageous computer program for limiting the torque build-up of an engine of a motor vehicle.
    A further object of the invention is to provide a method, an apparatus and a computer program for improving the performance of a motor vehicle. A further object of the invention is to provide an alternative method, an alternative device and an alternative computer program for effecting limitation of torque build-up of an engine of a motor vehicle.
    These objects with a method for achieving limitation of torque build-up of an engine in a motor vehicle according to claim 1.
    According to one aspect of the present invention, there is provided a method of limiting the torque build-up of an engine of a motor vehicle.
    The method comprises the steps of: - continuously identifying a process with respect to a maximum permissible motor torque; and - at the torque request, directing the torque build-up towards the requested motor torque, - at the torque request, continuously determining a difference between said maximum permissible motor torque and a prevailing motor torque; and - controlling torque build-up so that the motor torque resulting from the control is a function of said continuously determined difference. Said request of motor torque may be a request of motor torque in excess of said maximum permissible motor torque.
    By limiting torque build-up as a function of the difference between a prevailing motor torque and a maximum permissible motor torque, which maximum permissible motor torque is defined by a torque limiter, an initial desired response can be achieved without unnecessary time delays.
    Furthermore, a torque build-up is advantageous when a prevailing torque approaches the maximum achieved, soft behavior of the permitted motor torque is achieved. 10 15 20 25 30 Said torque construction can refer to starting the vehicle from a standstill.
    This results in an improved performance of the vehicle because transients of the vehicle's driveline are advantageously reduced with the innovative method. When starting from a standstill, a motor torque that exceeds a maximum permissible motor torque is often requested. According to the invention, both an initially desirable torque build-up and a smooth behavior are achieved when a prevailing motor torque approaches a maximum permissible motor torque.
    It should be pointed out that the method according to the invention can also be applicable to a vehicle which is propelled at a certain speed.
    Said function can represent a concave curve from below in a coordinate system for motor torque and time. This provides a desirable functionality of the vehicle which results in less heeling of the vehicle during operation. Said function may be a quadratic function.
    The method may further comprise the step of: - when said difference is zero, activating control of motor torque according to a function representing said maximum permissible motor torque.
    In this case, an efficient switch between drivers according to the innovative procedure and other drivers, which e.g. can control torque build-up according to a function on the basis of only the maximum permitted motor torque.
    Occurrence of oscillations or heeling of the vehicle will be eliminated or reduced to a minimum.
    The method may further comprise the step of: - continuously normalizing said determined difference with a maximum available engine torque. unique In this case, the innovative procedure can individual vehicle. Said standardization will take into account the engine performance of each adapted to each individual vehicle individual. A model for the maximum available engine torque for different speeds of the engine can be stored in a memory of a control unit of the vehicle.
    The method may further comprise the step of: - selecting the curve sequence of said function on the basis of the desired characteristic of said torque structure. In this case, a driver can influence torque build-up by selecting an operating mode. Examples of operating modes can be environmental modes, sports modes or normal modes. This provides a versatile and user-friendly method according to one aspect of the present invention.
    The method may include the step of activating said control of the torque build-up upon a request of a motor torque exceeding said maximum allowable motor torque. In this case, the innovative procedure is activated only when a rapid torque build-up is requested by e.g. a driver or other engine torque requester, for example a cruise control function stored in a control unit.
    The procedure is easy to implement in existing motor vehicles. Software for limiting torque build-up of an engine in a motor vehicle according to the invention can be installed in a control unit of the vehicle in the manufacture of the same. A buyer of the vehicle can thus be given the opportunity to choose the function of the procedure as an option. Alternatively, software including program code for performing the innovative torque build-up procedure of an engine in a motor vehicle may be installed in a control unit of the vehicle when upgrading at a service station. In this case, the software can be loaded into a memory in the control unit. Implementation of the innovative procedure is thus cost-effective, especially since no additional vehicle components need to be installed in the vehicle. The required hardware is already present in the vehicle today. The invention thus provides a cost-effective solution to the above problems. Software that includes program code for limiting the torque build-up of an engine in a motor vehicle can be easily updated or replaced. Furthermore, different parts of the software which include program code for limiting the torque build-up of an engine in a motor vehicle can be replaced independently of each other. This modular configuration is advantageous from a maintenance perspective.

The device comprises: - means for continuously identifying a process with respect to a maximum permissible motor torque; and - means for, when requesting torque, controlling said torque structure against the requested motor torque, - means for continuously, when requesting motor torque, continuously determining a difference between said maximum permissible motor torque and a prevailing motor torque; and - means for controlling torque build-up so that the motor torque resulting from the control is a function of said continuously determined velocity.
    In the device, said torque structure can refer to starting the vehicle from a standstill.
    In the device, said function may represent a concave curve from below in a coordinate system for motor torque and time. In the device, said function may be a quadratic function.
    The device may further comprise: - means for, when said difference is zero, activating control of motor torque according to a function representing said maximum permissible motor torque. The device may further comprise: - means for continuously normalizing said determined difference with a maximum available motor torque.
