Taking a series hybrid electric vehicle as an example, its working principle is as follows: At the beginning of the vehicle's operation, the battery is in a fully charged state, and its energy output can meet the vehicle's requirements, so the auxiliary power system does not need to work; when the battery level drops below 60%, the auxiliary power system starts. Relevant details are as follows: 1. Vehicle energy demand: When the vehicle's energy demand is high, the auxiliary power system and the battery pack simultaneously provide energy to the drive system; when the vehicle's energy demand is low, the auxiliary power system not only provides energy to the drive system but also charges the battery pack. 2. Battery pack: The presence of the battery pack allows the engine to operate under relatively stable conditions, thereby improving its emissions. Not all hybrid vehicles rely on electric motors, batteries, and wires. Some vehicles are driven by the combined action of hydraulic motors, flywheels, and accumulators.

What are the reasons why a dash cam won't turn on?

The reasons why a dash cam won't turn on: It could be due to a drained or damaged battery. If the dash cam can turn on when connected to an external power source, it indicates that the built-in battery is damaged or the voltage is too low to power it on. If the dash cam fails to turn on because of a drained battery, you can power it using an external power source or simply replace the battery. A dash cam is a device that records images, sounds, and related information during vehicle travel. Installing a dash cam can record the entire driving process in video and audio, providing evidence in case of traffic accidents. For those who enjoy self-driving tours, it can also be used to document the process of overcoming challenges and difficulties.

Which is Better: Cruise Control or Adaptive Cruise Control?

From the perspectives of safety and comfort, adaptive cruise control offers more advantages. Below are the differences between adaptive cruise control and cruise control: 1. Control Module: The adaptive cruise control system includes radar sensors, digital signal processors, and control modules; cruise control is relatively simpler, without complex sensors or processors. 2. Applicable Road Conditions: Adaptive cruise control can be used not only on highways but also in urban traffic conditions; cruise control is only suitable for good road conditions, such as highways or roads with light traffic. 3. Functionality: The most basic function of adaptive cruise control is to maintain the vehicle's longitudinal movement. In case of a collision risk, the vehicle will alert the driver and actively intervene with braking; cruise control relies solely on the driver's manual operation in emergencies.
