Recently, Volvo has been testing its new electric trucks, just like our previous content "345 km range Volvo pure electric FH heavy truck test performance is outstanding". Last time it was about the power performance and driving experience in the vehicle transport road test, and today I am ready to introduce two innovative features, in which the new safety configuration is extremely practical, after all, Volvo has always been serious about safety.
In the previous test, the vehicle with goods drove according to normal road conditions, through the actual operation to test whether the power system and endurance can meet the demand, while the actual comparison of electric vehicles and fuel vehicles in the driving, according to the tester's data monitoring found that pure electric vehicles are more responsive than diesel vehicles. Drivers, on the other hand, feel more comfortable and stable to maneuver, and the noise inside the cab is much smaller than in diesel cars.
The first function is called "ready to run", which is actually what we often call the early hot car, but Volvo's early hot car can be opened remotely. This function first ensures that the vehicle can start normally no matter what extreme environment it encounters. The test site was chosen in a small village called Arjeplog in northern Sweden, which is close to the Arctic Circle and the night temperature is often below -25 °C.
After that, it is necessary to be able to remotely control the vehicle, and the warm-up and pre-cooling functions of the vehicle can be activated remotely through the mobile phone. The specific situation of the driver can be determined according to the outdoor situation, this function in addition to the cab temperature can be more comfortable, avoid the summer like the oven in the winter like the freezer situation. There is also an early "preheating" of the battery, which can achieve the effect of the driver's "people to go". According to Volvo's data, the best operating temperature of the car's battery is about +25 ° C, so through this function, the battery is heated up and down in advance, which can allow it to wait for the driver to start in the best state.
Safety has always been Volvo's relentless pursuit, whether it is the safety of people, vehicles or cargo safety is a key focus project. This new configuration can increase the safety factor of the above three forms, which is Volvo's patented active grip safety control system. The main function of this control system is to improve the stability, acceleration and braking force of the vehicle under slippery road conditions. It is mainly ordinary roads in rain and snow, even including slippery gravel roads. Tested in cargo situations with volvo FH electric trucks equipped with the system, the results showed a 45% improvement in grip at maximum acceleration.
Anna Wrige Berling, Volvo Trucks' director of traffic and product safety, said the improvement in grip was noticeable when driving on slippery gravel roads, and he thought customers in the construction industry would prefer the system that increased productivity.
The system works by means that when the truck starts to slip, multiple sensors will react to the road surface situation to the vehicle's active grip control system, at which point the system will obtain interference with some vehicle control, and use the vehicle motor and other execution units to help the driver stabilize the vehicle through intelligent analysis. Because the electric motor can respond faster than the driver, the force generated between the wheel and the road can be controlled in an instant, actively preventing the wheel from slipping.
The system first reflects two advantages, the first is to improve the driver's ability to adapt to special road conditions and environments, even if the experience is slightly lacking, it can complete some difficult tasks. The second is to improve work efficiency, which is due to the active control of the grip to improve the braking performance of the vehicle, so that the operation has been completed before the ABS system is started, reducing some intermediate operation time and achieving a smoother braking experience.
This Volvo active grip control system will be used on heavy-duty electric trucks, including the electric models of the FH, FM and FMX series. There is also a version of this feature that will be available on diesel or natural gas models. After reading what you want to say, or want to know which brand models, welcome to leave a message to tell me.
