Method, device, and computer program product for determining a further test route during a test drive of a transportation vehicle

A non-transitory computer program product including computer-implemented instructions for carrying out a method for determining a further test route and updating route guidance for a transportation vehicle for reaching a target load value in real time during a test run based on loads which are applied to the transportation vehicle, a transportation vehicle position and route options available based on the transportation vehicle position, when the computer-implemented instructions are performed on a computer processor to provide a calculation unit, wherein the computer-implemented instructions comprise:

• linking the transportation vehicle position, determined by a position-determining apparatus, on a section of road, road information about this section of road composed of loads which are applied to the transportation vehicle and sensed by a sensor apparatus and stored in a memory apparatus and determine a load characteristic value for this section of road;
• retrieving a test state of the transportation vehicle from the memory apparatus, the test state comprising all the loads that have already been applied to the transportation vehicle up to a point when the test state was last updated;
• calculating an updated test state of the transportation vehicle from the retrieved test state and the load characteristic value and storing the updated test state in the memory apparatus;
• determining turn possibilities at the end of the section of road and a utility value of each of the turn possibilities in respect to attaining the target load value based on the road information and loads which are expected and are stored in the memory apparatus for the transportation vehicle, wherein the road information and loads which are expected are repeatedly calculated for a next predefined number, n, of road segments throughout the test state;
• selecting the turn possibility with the highest utility value to attain the target load value based on a totality of loads to be applied and other loads that have already been applied to achieve a maximum test state as efficiently as possible, and
• updating a route guidance display with the selected possibility.

A method for determining a further test route and updating route guidance for a transportation vehicle for reaching a target load value during a test run based on loads which are applied to the transportation vehicle, a transportation vehicle position and route options available based on the transportation vehicle position, wherein at least the following operations are carried out by a calculation unit:

• linking the transportation vehicle position, determined by a position-determining apparatus, on a section of road, road information about this section of road composed of loads which are applied to the transportation vehicle, sensed by a sensor apparatus and stored in a memory apparatus, and determining a load characteristic value for this section of road;
• retrieving a test state of the transportation vehicle from the memory apparatus, the test state comprising all the loads that have already been applied to the transportation vehicle up to a point when the test state was last updated;
• calculating an updated test state of the transportation vehicle from the retrieved test state and the load characteristic value and storing the updated test state in the memory apparatus;
• determining turn possibilities of at the end of the section of road and a utility value of each of the turn possibilities in respect of attaining the target load value based on the road information and loads which are expected and are stored in the memory apparatus for the transportation vehicle, wherein the road information and loads which are expected are repeatedly calculated for a next predefined number, n, of road segments throughout the test state;
• selecting the turn possibility with the highest utility value to attain the target load value based on a totality of loads to be applied and other loads that have already been applied to achieve a maximum test state as efficiently as possible, and
• updating a route guidance display with the selected possibility.
