An intelligent self-locking system of clutch which uses MC9S12XS128MAL as the main microcontroller was designed in this research. The system detects whether the door is completely closed or not by the position switch installed in the door rail to achieve control of the clutch pedal. When the door of bus is not completely closed, the driver cannot push down the clutch pedal to drive the bus. Doing that can we achieve automotive driver assistance and further improve driving safety. This paper also discusses the design of the system’s hardware circuitry and procedures.

Ergonomic Evaluation

Aimed at the drawbacks of traditional method of spot evaluation for tractor cabs, such as low effectiveness and high expense, this paper established a new method of tractor cab design and evaluation, which included formulating ergonomic evaluation process, creating virtual models of tractor cab and operators, building virtual environment of tractor cab man-machine system and conducting ergonomic evaluation. The YTO-1604 wheeled tractor has been taken as the analysis object, the layouts of its seat, accelerator pedal, clutch pedal, brake pedal, gear shift lever, steering wheel and other major parts were optimized. The optimized model was created by UG, then it was imported into JACK, thus the object for analysis was created. To accommodate the Chinese tractor operator population, the 95th, 50th and 5th percentile virtual operator models which respectively stands for the big figure, medium figure and small figure of Chinese adult males for ergonomic evaluation were created in JACK, and the angular comfort range for human body joints were determined. The 50th percentile operator was adjusted to a cozy posture through human control module, with hands holding steering wheel, left foot naturally put on clutch pedal, while right foot flat placed on the floor. The operator was located to the h point of seat in the optimized cab model, thus the man-machine virtual environment was completely built. Then the reach zone of the 5th percentile operator and the visual field of the 95th percentile operator were generated, the 95th percentile operator’s comfort was evaluated and the forces of the 95th percentile operator’s spinal L4/L5 were calculated. The results showed that the gear shift lever, steering wheel and control panel were located in the accessible reach zones, conforming to manipulation requirements. Control panel and windshield (except for part of the side windshield which could be observed by moving head) were contained in the visual field, according with vision design standard. The overall comfort score of the 95th percentile operator’s different body parts was 24.5, which indicated that the operator was in good condition and the design conformed to physiological requirements. The lower back compression force of the 95th percentile operator was 742, representing a nominal risk of lower back injury for operators. Thus, the rationality of cab layout scheme was well verified. This paper provides a method for the ergonomic design and evaluation of tractor cabs.

Based on biomechanic theory, the comfort evaluation can be made to aim at improving the comfort of clutch operation of light commercial vehicle. First, the virtual model of the cab was established to predict posture of pressing clutch pedal. Then values of joint toques were figured out by using Jacobin Method and these data were brought into the comfort evaluation function to achieve the comfort degree of clutch operation. From the perspective of biomechanics, this research reveals the cause of clutch operation discomfort in a deeper sense and will provide a new reference approach for improving operation comfort of light commercial vehicle.

The Relationship

In this research, a virtual cab package model had been established in CATIA which was used for driving posture prediction in RAMSIS. 40 cab package schemes and the corresponding driving postures could be acquired by adjusting the parameters of the steering wheel, the clutch pedal and the seat. The quantitative analysis between cab package parameters and driving posture was researched using regression method. And the regression functions that clearly express the relationship between them were concluded, which could be used for directing the design and optimization of the cab package schemes.
