Abstract

Method of route planning for physical training, wherein the heart rate of the subject should be kept within a permitted range. Prior to route planning, map data including starting and target points and altitude data are stored. A load profile is created by measuring the heart rate of the subject along routes of different steepness and storing the data in an electronic table, taking into account the required effort and whether the subject could have partially regenerated. The route planning includes searching and selecting a possible route, dividing the route into segments of steepness, and determining the costs based on the steepness data. The cost represents the load when the subject takes that section. Next, expected heart rate is calculated and it is determined whether it will remain in the permitted range along the whole first route. If the heart rate will be in the permitted range, the route is permitted, if not, the steps are repeated for subsequent possible routes where the heart rate in the associated route will remain in the permitted range.

Claims

1. Method of route planning for physical training purposes, wherein during movement along a planned route the heart rate of the training subject should be kept within a permitted range;

comprising the steps of;

as preparatory steps prior to the actual route planning;

storing in a navigation device map data of an area concerned that includes required starting and target points, the map data include also altitude data;

determining a load profile of the subject including;

measuring the heart rate of the subject along routes of different steepness;

storing the so obtained data in an electronic table stored in the device;

the actual route planning includes the further steps of;

searching possible routes between said starting and target points;

selecting a first one of the possible routes and

dividing the first possible route into segments that have respective constant steepness;

determining the respective costs typical of each section based on the steepness data of the section using the table of said stored load profile, wherein the cost represents the load when the subject takes that section;

calculating from the determined cost values in the course of the movement of the subject proceeding along said first possible route his expected heart rate;

examining whether the expected heart rate will remain in the permitted range along the whole first route;

accepting the first route as planned route if the examination shows that the heart rate will be in the permitted range; and

repeating the planning steps for subsequent possible routes as long as the examination at a route shows that the heart rate in the associated route will remain in the permitted range, and accepting that route as the planned routed, characterized in, that during the step of determining the load profile the time elapsed since the beginning of the movement is also stored in said table, and said determination step is carried out repeatedly and the extent of regeneration of the subject is determined as a result of a larger load followed by a smaller load; and

at said calculation step of the expected heart rate the cost of any section depends also on the time elapsed since the beginning of the movement and the total load during said elapsed time; and

in said calculating step examining at each section whether at the previous section or sections there was a decrease in the required level of effort in which the subject could have partially regenerated and if such is experienced the previously determined regeneration is also taken into account in determining the cost associated with the concerned section.

2. The method as claimed in claim 1, wherein navigating the subject with the navigation device along said accepted planned route.

3. The method as claimed in claim 1, wherein said starting and target points are the same, said route is planned on the basis of a predetermined training time and/or so that the heart rate of the subject remains in the permitted range.

4. The method as claimed in claim 2, wherein during movement along the planned route monitoring the heart rate of the subject and comparing the actual heart rate with the calculated expected value for the given point of the route, and if a definite increase has been experienced, repeating the determination of the costs for the remaining part of the route by using the measured actual heart rate, and if the repeated determination shows that the expected heart rate along the originally planned route would cross said permitted range, notifying the subject about the potential overload.

5. The method as claimed in claim 4, wherein after or instead of said notifying step starting a new search for an alternative route, and if such is found, navigation the subject along this route.

6. The method as claimed in claim 4, wherein the training is carried out by the subject by using a vehicle equipped with a partially electric drive, in which the proportion of the electric and human drive components can be adjusted;

and after said notifying step or instead of it increasing the ratio of the electric drive component by the required extent compared to the human contribution component.
