Abstract

a presente invenção refere-se a um método para a adaptação da velocidade de um veículo quando se realiza uma curva. o método compreende a etapa de controlar (s1) a velocidade do veículo e, nesse caso, limitar o aumento de uma velocidade instantânea máxima permitida com base na taxa de alteração de ângulo da posição do volante de tal forma que o aumento até um determinado ponto seja permitido apenas quando a taxa de alteração de ângulo tiver caído abaixo de um valor predeterminado. a presente invenção também se refere a um sistema para a adaptação da velocidade de um veículo quando se realiza uma curva. a presente invenção também se refere a um veículo motorizado. a presente invenção também se refere a um programa de computador e a um produto de programa de computador.The present invention relates to a method for adapting a vehicle's speed when cornering. The method comprises the step of controlling (s1) the vehicle speed and, in that case, limiting the increase of a maximum permissible instantaneous speed based on the rate of change of steering wheel angle such that the increase to a certain point. only be allowed when the angle change rate has fallen below a predetermined The present invention also relates to a system for adapting a vehicle's speed when cornering. The present invention also relates to a motor vehicle. The present invention also relates to a computer program and a computer program product.
