Abstract

método de acionamento de mudança de marcha em veículo alimentado com combustível flexível de etanol. método de acionamento de mudança de marcha em veículo alimentado com combustível flexível de etanol, compreendendo as seguintes etapas: (1) determinar uma razão de velocidade i de uma razão de uma velocidade de rotação nout do eixo de saída da caixa de câmbio e uma velocidade de rotação n do motor; (2) comparar a razão de velocidade i com razões de velocidade das respectivas engrenagens na caixa de câmbio para determinar a engrenagem do veículo; (3) determinação de um coeficiente de adaptação de acordo com a rotação determinada na etapa (2), e de acordo com o coeficiente de adaptação e a concentração de combustível atual a%, ajustar uma velocidade do veículo na mudança de velocidades com base na concentração de combustível atual a%; e (4) quando a velocidade do veículo atingir a velocidade do veículo em mudança de velocidades da etapa (3), acionar a mudança de uma engrenagem do veículo. o método de acionamento de mudança de marcha executa o ajuste para alcançar a regra de mudança de engrenagem mais econômica de acordo com uma concentração de etanol, permitindo assim que o veículo sempre acione o motorista para trocar de marcha em uma zona econômica de mudança de velocidade e melhorando assim a economia de combustível do veículo.shifting drive method in a vehicle fueled by flexible ethanol fuel. The shifting method of a fuel-efficient ethanol fueled vehicle, comprising the following steps: (1) determining a speed ratio i of a ratio of a gearbox output shaft nout rotation speed and a engine speed n; (2) comparing the speed ratio i to the gear ratios of the respective gearboxes to determine the gear of the vehicle; (3) determining an adaptation coefficient according to the rotation determined in step (2), and according to the adaptation coefficient and actual fuel concentration at%, adjusting a vehicle speed in gear shifting based on the current fuel concentration at%; and (4) when the vehicle speed reaches the shifting vehicle speed of step (3), triggering the shift of a vehicle gear. the gear shift method performs the adjustment to achieve the most economical gear change rule according to an ethanol concentration, thus allowing the vehicle to always drive the driver to shift in an economical gear change zone and thus improving the fuel economy of the vehicle.
