VEHICLE CONTROL METHOD AND APPARATUS

The present disclosure relates to a method of generating a target operational speed band () for a host vehicle () travelling along a route. A first time-dependent obstacle (--) is identified at a first location on the route. The first time-dependent obstacle (--) is identified as hindering progress of the host vehicle () during a first time period (I). The first time-dependent obstacle (--) is defined in a two-dimensional speed against distance map (). A first speed trajectory () is determined from a first point to a second point within the two-dimensional speed against distance map (). The second point represents the first location on the route and the determined first speed trajectory () represents the host vehicle () arriving at the first location at a first arrival time. The target operational speed band () is determined such that the first speed trajectory () forms one of an upper limit and a lower limit of the target operational speed band (). The first arrival time is outside said first time period (I). The present disclosure also relates to a controller () for generating a target operational speed band (); and to a vehicle ().
