在欧洲卡片项目（尤里卡1924年）的框架内，在雷诺动态模拟器上进行了几个实验。目的是评估运动平台在执行基本驾驶任务（如在十字路口刹车和转弯）时提供的动觉线索的贡献。在制动实验中，11名标准驾驶员被要求重复以下顺序16次：达到目标速度（80公里/小时），保持该速度不变，然后减速，以便在尽可能靠近特定路标的地方停车。连续8次试验激活运动平台，其余8次试验不激活运动平台（或相反）。结果表明，运动恢复可以防止受试者达到过高和不切实际的减速，这是在静态模拟器中观察到的。此外，在静态模式下，随着驾驶员不断增加制动力，制动行为也出现了适应性，而在运动提示下，制动策略保持稳定。通过分析制动行为的第一秒和各自的平台运动，特别讨论了这一结果。在转弯实验中，司机在模拟的无交通的城市环境中绕一个方形城市街区转2圈，在四种平台条件下。在这些条件下，侧向信号（单独的摇摆+翻滚），纵向信号（单独的浪涌+俯仰），两者都被恢复或没有被恢复。运动线索的存在对被驱动车辆在每个90°曲线内的轨迹模式产生全局影响。这些实验是在驾驶时感觉运动整合的背景下讨论的。运动线索（即使振幅有限）可以作为额外输入集成到驾驶员控制回路中，前提是它们与所考虑的驾驶任务相关。
In the framework of the European CARDS Project (Eureka n°1924) several experiments were carried out on the Renault Dynamic Simulator. The objective was to assess the contribution of kinesthetic cues provided by the motion platform when executing elementary driving tasks: braking and cornering at intersections. In the braking experiment, 11 standard drivers were asked to repeat 16 times the following sequence: reach a target velocity (80 km/h), maintain this velocity constant and decelerate in order to stop as close as possible to a specific signpost. Motion platform was activated for eight successive trials and inactivated for the remaining eight trials (or reverse). Results show that motion restitution prevents subjects from reaching too high and unrealistic decelerations, which are observed in a static simulator. Moreover, an adaptation of braking behavior appears in static mode, as drivers apply increasing braking force trial after trial, whereas braking strategy remained stable in the presence of motion cues. This result is discussed in particular by analysing the first seconds of braking behaviour and respective platform motion. In the cornering experiment, drivers took 2 laps around a square city block in a simulated urban environment free of traffic, in each of four platform conditions. In these conditions, lateral cues (sway+roll alone), longitudinal cues (surge+pitch alone), both of them or none were restituted, respectively. A global effect of the presence of the motion cueing shows on the trajectory pattern of the driven vehicle inside each 90° curve. These experiments are discussed in the context of sensorimotor integration while driving. Motion cues -when present even with limited amplitude- may be integrated in the driver control loop as additional inputs, providing they are relevant to the driving task considered.
