【摘要】 按不同的制动控制策略,将混合动力汽车再生制动系统分为具有最佳制动效果的串联制动、具有最佳能量回收率的串联制动和并联制动3种类型,并分别对它们进行了分析。提出了基于SOC、车速和制动踏板位置,动态地控制再生制动转矩的控制策略,并将其应用于一款并联混合动力汽车上。测试结果表明:所制定的制动控制策略,可在保证安全的前提下,更多地回收制动能量,并有较好的制动感觉。更多还原

【Abstract】 According to different braking control strategies,the regenerative braking systems of hybrid electric vehicle(HEV) are classified into three categories: series braking with the best braking effect,series braking with the maximum energy regeneration rate and parallel braking,which are then analyzed respectively.A control strategy is put forward based on SOC,vehicle speed and the position of braking pedal,and is applied to a typical parallel HEV.The test results show that the braking control strategy proposed can recovery more braking energy with better braking feeling on the premise of safety assurance.更多还原
